1) Abu Bakr said: “Hazrat Abu Talib (as) didn’t die until he had said: There is no God but Allah and Muhammad(s.a.w.w) is the Messenger of Allah (s.a.w.a.).”
(SharhNahjulBalagha, vol. 3, p. 312, SheikhulAbtah, p. 71, al-Ghadeer, vol. 7, p. 370, 401, Aayaan ash-Shia, vol. 39, p. 136)
2) The great companion Abu Zarr, whose eyes hadn’t been blinded by the shine of gold nor had he been frightened by the violence of Mo’awiya said:
“By Allah, whom there is no god other than! Hazrat Abu Talib (as) didn’t die until he became a Muslim ...”
(Al-Ghadeer, vol. 7, p. 399)
3)Abdullah bin Abbas was asked by a man: “O cousin of the Messenger of Allah (s.a.w.a.)! Would you tell me about Hazrat Abu Talib (as)? Was he a Muslim or not?”
Abdullah bin Abbas answered him: “How was he not a Muslim whereas he said:
“They knew well that our son had never been a liar, nor had he cared for absurdities.”
(Al-Hujja, p. 94, 115, al-Ghadeer, vol. 7, p. 397)
4)Hassaan bin Saabit, the poet recited:
“If you mourn a dead,
Please, mourn the loyal man; the brother of the loyal.”
Sibt bin aj-Jawzi when explaining this verse said: “He means Hamza and Hazrat Abu Talib (as).”
(TazkeratulKhawaas, p. 31)
These confessions were not limited to a certain age rather than the others or to a certain class of people ... everyone, who was honest, fair, impartial and not affected by the different fancies, had a ray of light emitted in the darkness to light the straight way.
5)It was a word of rightness emitted of the mouth of the Abbasid King Abdullah al-Ma’moon, although he was not such an honest man, but it was a fair word that slipped away of his mouth willingly or unwillingly. He said: “By Allah, Hazrat Abu Talib (as) became a Muslim when he said:
I supported the Prophet; the Prophet of the Lord,
with swords shining like the lightening.
I defended and protected the Prophet of the Lord,
as kind guardian.
I creep to his enemies like a young camel with much heed,
but I roar at them proudly,
as a lion roaring in its liar
(SharhNahjulBalagha, vol. 3, p. 314, al-Ghadeer, vol. 7, p. 337, Al-Hujja, p. 54, Divan Abu Taalib, p. 10, The Theses of al-jahidh, p. 32.)
