Ali ibn Abi Talib: The Fourth Rightly-Guided Caliph and Cousin of the Prophet ﷺ (UK Profile 2026)

Ali ibn Abi Talib (Arabic: علي بن أبي طالب; born 23 BH / 599 CE, died 40 AH / 661 CE) was the cousin and son-in-law of the Prophet Muhammad ﷺ, the fourth Rightly-Guided Caliph (Khulafa Rashidun), one of the most learned of all the Sahabah, and one of the ten Companions promised Paradise (al-ʿasharah al-mubasharoon). Among Sunni Muslims he is universally revered as one of the four greatest Caliphs; among Shi'a Muslims he is held to be the Prophet's ﷺ direct successor and the first of the twelve Imams. This UK guide presents Ali (RA)'s life from the Sunni perspective — his birth, his close relationship with the Prophet ﷺ, his role in early Islam, his Caliphate, and what British Muslim families can take from his example.

His birth inside the Ka'bah

Ali (RA) was born in 599 CE inside the Ka'bah itself in Makkah — an honour preserved for him alone in Islamic history. His mother, Fatimah bint Asad, was visiting the Ka'bah in late pregnancy when labour began. The doors of the Ka'bah, normally locked, were said to have opened miraculously to allow her to enter, and she gave birth to him within the sacred structure. Classical sources (al-Tabari, al-Hakim, others) record this without contradiction. Ali (RA) is the only person known to have been born inside the Ka'bah.

His father, Abu Talib ibn Abd al-Muttalib, was the Prophet's ﷺ paternal uncle — the same uncle who raised the orphaned young Muhammad ﷺ after his grandfather's death. This made Ali (RA) the Prophet's ﷺ first cousin.

The first male child to embrace Islam

When the Prophet ﷺ began receiving revelation in 610 CE at age 40, Ali (RA) was about ten years old and was living in the Prophet's ﷺ household. The young Ali (RA) embraced Islam very early — he is widely regarded as the first male child to do so. The first adult Muslims were Khadijah (RA) (the Prophet's ﷺ wife), Abu Bakr (RA) (his closest friend), and Zayd ibn Harithah (RA) (his freed slave and adopted son).

Ali's (RA) early embrace shaped the rest of his life: he grew up entirely within the Muslim community, witnessed the persecution of the Makkan period, and was 23 years old at the Hijrah.

The night of the Hijrah: sleeping in the Prophet's ﷺ bed

One of the most famous moments of Ali's (RA) early life: on the night of the Hijrah in 622 CE, Quraysh assassins from each clan had gathered around the Prophet's ﷺ house with the intention of killing him together (so that no single clan could be held responsible for revenge). Allah commanded the Prophet ﷺ to leave that night with Abu Bakr (RA). To delay the assassins' discovery, Ali (RA) volunteered to sleep in the Prophet's ﷺ bed wrapped in his green cloak, knowing that the assassins might kill him when they entered.

The Prophet ﷺ and Abu Bakr (RA) escaped to the Cave of Thawr; the assassins waited until morning before storming the house, only to find Ali (RA) instead of the Prophet ﷺ. Surah Al-Baqarah 2:207 is widely understood to refer to this episode: "And of the people is he who sells his soul, seeking the pleasure of Allah."

Ali (RA) then stayed in Makkah for several days to return the deposits people had left with the Prophet ﷺ for safekeeping, before himself migrating to Madinah on foot — a 400 km journey he completed alone.

His marriage to Fatimah (RA)

In 2 AH (624 CE), shortly after the Battle of Badr, Ali (RA) married Fatimah (RA), the youngest daughter of the Prophet ﷺ. The marriage produced four children who survived to adulthood: Hassan (RA), Hussain (RA), Zaynab, and Umm Kulthum. Through Hassan (RA) and Hussain (RA), virtually all of the Ahl al-Bayt (people of the household) lineage descends to the present day.

The household of Ali (RA) and Fatimah (RA) lived in deliberate simplicity. Despite Ali (RA) being the Prophet's ﷺ son-in-law and a senior companion, the family ground their own grain, mended their own clothes, and lived without servants for most of their marriage. The Prophet ﷺ taught them a beautiful supplication for moments of fatigue: 33 Subhanallah, 33 Alhamdulillah, 34 Allahu Akbar before sleep — "better than a servant" (Sahih al-Bukhari 5361). British Muslim families struggling with daily fatigue can recite the same.

His role in the Prophetic battles

Ali (RA) participated in nearly every battle of the Prophet ﷺ — Badr, Uhud, Khandaq, Khaybar, Hudaybiyyah, the Conquest of Makkah, and Hunayn. At Khaybar (7 AH), the Prophet ﷺ said about him: "Tomorrow I will give the standard to a man who loves Allah and His Messenger, and Allah and His Messenger love him. Allah will grant victory through his hand." The next morning he gave the standard to Ali (RA), who led the conquest of the fortress.

Ali (RA) was renowned for his physical courage in single combat — the Arab tradition of one-on-one challenges before the main battle. His sword, Dhu'l-Faqar, became one of the most celebrated weapons in Islamic memory. But his contemporaries also note he was reluctant to fight, preferring resolution by speech where possible.

Caliphate (35-40 AH / 656-661 CE)

Ali (RA) became the fourth Caliph in 35 AH after the assassination of Uthman (RA). His five-year Caliphate was the most difficult of the four, dominated by the First Civil War (Fitnah):

• The Battle of the Camel (36 AH). Aisha (RA), Talha (RA), and Az-Zubayr (RA) led an army demanding immediate justice for Uthman's (RA) assassination. Ali (RA) sought to investigate first, then prosecute. The two sides met at Basra; the battle was fought reluctantly. Aisha (RA) was returned to Madinah with full honour after the battle.
• The Battle of Siffin (37 AH). Muawiya ibn Abi Sufyan (RA), governor of Syria, refused to recognise Ali's (RA) Caliphate until Uthman's (RA) killers were brought to justice. The two armies fought at Siffin for several months without decisive victory; arbitration was agreed.
• The Khawarij rebellion (38 AH). A group within Ali's (RA) own army split off, declaring both Ali (RA) and Muawiya (RA) infidels for accepting arbitration. Ali (RA) defeated them at Nahrawan but their movement persisted as a permanent extremist sect.
• His assassination (40 AH). A Khariji extremist named Ibn Muljam attacked Ali (RA) with a poisoned sword while he was leaving Fajr salah at the mosque of Kufa on the 19th of Ramadan 40 AH. Ali (RA) died two days later, on the 21st of Ramadan.

His son Hassan (RA) was given bayʿah as the fifth Caliph but, as we covered in our Al-Hassan ibn Ali UK profile, abdicated within months to end the civil war.

His scholarship

Ali (RA) was one of the most learned of all the Sahabah. The Prophet ﷺ said about him: "I am the city of knowledge, and Ali is its gate" (Sunan al-Tirmidhi 3723; the chain is debated, but the meaning is broadly accepted). Specific contributions:

• One of the few companions who recorded ahadith in writing during the Prophet's ﷺ lifetime (similar to Abdallah ibn Amr ibn al-Aas).
• One of the foremost authorities on the Quran's nasikh wa mansukh (abrogating and abrogated verses).
• Eloquence in Arabic. His sermons preserved in Nahj al-Balagha are among the most quoted classical Arabic prose, studied by Sunni and Shi'a scholars alike.
• Senior judge during the Caliphates of Abu Bakr (RA), Umar (RA), and Uthman (RA), to whom they often deferred for difficult legal questions.

His character

Ali (RA) was famous for:

• Asceticism. Despite being the son-in-law of the Prophet ﷺ and Caliph, his clothes were often patched. He owned little.
• Justice. As Caliph he refused to favour his own family in any judgement.
• Generosity. The Quranic ayah on giving charity at night and during the day (Surah Al-Baqarah 2:274) was, according to several tafsir reports, revealed about his giving.
• Courage in combat and humility outside it.

What British Muslim families can take from Ali (RA)'s life

• Embrace Islam early and live it daily. Ali (RA) embraced Islam at about age 10 and lived it for 51 years until his death. UK Muslim children who internalise the deen early carry it differently than late-converts.
• Knowledge is the highest pursuit. The Prophet ﷺ specifically called Ali (RA) the gate to the city of knowledge. UK Muslim teenagers should pursue Quranic and Arabic learning seriously, not as a hobby.
• Live simply regardless of position. Ali (RA) was Caliph and wore patched clothes. UK Muslim professionals' status should not match their consumption habits.
• Justice over loyalty. Ali (RA) refused to favour his own family. British Muslim community leaders facing pressure to bend rules for relatives should follow his example.
• Dignity in adversity. Ali's (RA) Caliphate was the hardest of the four; he never compromised on principles even when it cost him politically.

The Sunni-Shi'a difference, briefly

For British Muslim families: the Sunni-Shi'a difference centres in part on the question of succession after the Prophet ﷺ. Sunnis hold that the community properly chose Abu Bakr (RA) as the first Caliph, with Umar (RA), Uthman (RA), and Ali (RA) following. Shi'a hold that Ali (RA) was designated by the Prophet ﷺ at Ghadir Khumm and should have been first.

This guide presents the Sunni perspective. We respect Ali (RA) deeply — he is one of the four Rightly-Guided Caliphs, one of the ten promised Paradise, the Prophet's ﷺ son-in-law, the father of Hassan (RA) and Hussain (RA). Sunni reverence for Ali (RA) is total, even where we differ on succession theory. UK Muslim children should learn his life with respect and avoid sectarian polemics where possible.
