Allaah is the One I ask and for Whose reply I hope: that He is benevolent to the brother in this life and the hereafter, that He brings about benefit by him and makes him blessed wherever he may be. Verily the blessing of a man lies in his teaching of goodness wherever he may be and his giving of advice to everyone he meets. Allaah, the Exalted said, informing about al-Maseeh (i.e., Jesus) (.): And He made me blessed wherever I may be. [Soorah Maryam (19):31].

Meaning, A teacher of goodness, a caller to Allaah, one who reminds (others) of Him and who exhorts them to His obedience.. So this is from the blessing of a man.
