Hazrat Ubay Bin Ka’ab رضي الله عنه narrates that Rasulullah said: “O Abu Mundhir..! Do you know which is the greatest verse in the book of Allah that you have?’ , I replied:
( اللّهُ لاَ إِلَـهَ إِلاَّ هُوَ الْحَيُّ الْقَيُّو )
“ Allah! La ilaha illa Huwa (none has the right to be worshipped but He), the Ever Living, the One Who sustains and protects all that exists.” [Al-Baqarah:255]
He hit my chest and said : "May knowledge delight and benefit you, O’ Abu Mundhir."(Muslim)
Mas’ala (Precept): when there is no apprehension of self obsession,one may be praised for his ilm and Taqwa in his very presence. The wisdom here is that people may gain knowledge from him as much as possible and benefit from him.
