For the sake of brevity...

For the sake of brevity, I am going to confine my self to a tradition occuring in the commentary of the Quran by Abi Is'haq Ahmad Ibn Muhammad ibn Ibrahim Nisaboori al-Tha'labi.

A few comments on the respected personality: He died in 337 AH and Ibn Khallikan gives an account of his death saying: "He was unique as a commentator of the Quran and his Tafsir al-Kabir is superior to all other interpretations." When he reached this verse he recorded this in his Tafsir al-Kabir on the authority of Abu Dhar al-Ghifari, who said: Both of my ears may turn deaf and both of my eyes may become blind if I speak a lie.

I heard the Messenger of Allah, Allah's blessings and peace be upon him and his posterity, saying, "Ali is the guide of the righteous and the slayer of the infidels. he who has helped him is victorious and he who has abandoned him is forsaken." One day I said my prayers in the company of the Prophet. A beggar came to the mosque and begged for alms, but nobody gave him anything. Ali was in a state of kneeling in the prayer.

He pointed out his ring to the beggar, who appraoched him and removed the ring from his finger. Thereupon the Prophet, Allah's blessings and peace be upon him and his posterity, implored Allah the Mighty and Glorious, saying: "O Allah!

My brother Moses begged you saying, 'My Lord, delight my heart and make my task easy and undo the knot in my tongue so that they may understand me, and appoint from my kinsmen, Haroon, my brother, as my vizier, and strenghthen my back with him and make him participate in my mission so that we may glorify You and remember You more frequently. Certainly You see us.' And You inspired him: 'O Musa! All your requests have been granted.' O Allah! I am your slave and your prophet.

Delight my heart and make my task easy and appoint from among my kinsmen Ali as my vizier and strengthen my back with him." Abu Dhar, then, proceeded By Allah, the Messenger of Allah, Allah's blessings and peace be upon him and his posterity had not yet finished his supplication when the trustworthy Gabriel descended to him with this Verse "Certainly Allah is Your Master, and His Prophet and those who believe who establish prayer and give charity while they bow.

And whoever takes Allah and His Messenger and those who believe as a guardian, so surely the party of Allah will be victorious." Sunni reference: Tafsir al-Kabir, by al-Tha'labi under the commentary of verses 5:55-56 of Quran.
