Sayyadi Ali Ibn Abi Talib (d. 661)

[yusuf72]

 As-Salaam alaikum,

  About that close Sahabi, Sayyadi Ali Ibn Abi Talib, may Allah be pleased with him, the Prophet Sallallahu alaihi Wasallam, said:--

       "Whoever wishes to find out about Adam's knowledge, Nuhu's piety,

       Ibrahim's friendliness, Musa'a power, and Isa's worship, should look

      at Ali, for he has all these virtues.''  (Reported by Bayhaqi in Fada'il al-Sahaba)

Also, Bayhaqi quoted Sayyadina Ali as having said: The Noble Prophet (Salla Allahu ta'ala 'alayhi wa Sallam),

Sallallahu alaihi Wasallam, gave me the mission to set out to Yemen for

passing judgement among them. Being surprised by the order and its referring to

me, i said: O Messenger of Allah! Do you assign me a judge while I am still

too young not knowing the principles of judgement! The Noble Prophet (Salla Allahu ta'ala 'alayhi wa Sallam) put his

hand on my chest, prayed for me and said: 'O Lord! Guide his hear, make his

tongue steadfast in telling the truth.'

Ali said: 'By the Lord who cleaves a grain in the earth, after this prayer, I did not

pass any judgement between two persons in which there was a bit of doubt.' (Dala'il al-Nubuwwah, vol 5)
