Some of the companions of the Holy Prophet (peace be upon him and his holy progeny) were seen to be constantly praising a particular person in his (peace be upon him and his holy progeny) presence. One day they saw him while they were with the Holy Prophet (peace be upon him and his holy progeny) and pointing to him said: That is the person whom we used to praise.
The Holy Prophet (peace be upon him and his holy progeny) looked at the person and said: I am witnessing on his face a satanic blackness. As the person came near and greeted him (peace be upon him and his holy progeny), the Holy Prophet (peace be upon him and his holy progeny) said to him: I place you under the oath of God; tell me, did you not say to yourself: “Amongst the companions of the Holy Prophet (peace be upon him and his holy progeny) there is none, who is superior to and better than me?” The person confessed: Yes, the thought did pass my mind.
(In this manner the Holy Prophet (peace be upon him and his holy progeny), by means of his inner vision, informed him of his inner conceit and pride.)( Shanidanihaa-e-Taareekh, pg. 378, Mahajjah al-Baidhaa, vol. 6, pg. 298. )
