Hazrat Abu-Taleb, the father of Imam Ali (AS) and the uncle and protector of Holy Prophet Mohammad (SAWA)
On 26th of the Islamic month of Rajab in the third year prior to Hijra, according to an account, Abu-Taleb, the father of Imam Ali (AS) and the uncle and protector of Prophet Mohammad (SAWA), passed away in Mecca. Along with his wife, Fatema bint Asad, upon the death of his father Abdul-Muttaleb, he took charge of the 8-year orphan of Abdullah, his deceased brother, and brought up the future Prophet as his own son.
Abu Taleb was a staunch monotheist following the creed of his ancestor, Prophet Abraham, and when God formally appointed his now 40-year old nephew as the Last and Greatest messenger to mankind, he firmly believed in the message of Islam and protected the Prophet against the taunts and even attacks of the pagan Arabs.
When the Meccans imposed the social-economic boycott of the Prophet, he took his nephew and the whole neo Muslim community under his protection to the safety of the gorge outside Mecca which is still called She'b Abi Taleb in his honour.
His death saddened the Holy Prophet and since the same year, the Holy Prophet's loyal wife, the Mother of all True Believers (Omm al-Momineen) Hazrat Khadija (SA) also passed away, the year is known as "Aam al-Hozn (Year of Grief).
