It is related in a Hadith that when an aalim intends to please his Creator with his knowledge, then everything else (in the world) will fear him. (i.e. he will have nothing to fear).
In another Hadith it is mentioned that if the ulama are not the friends of Allah, then in the hereafter Allah has no friend. Meaning that an aalim is in reality a wali. (Sakhaawi).
It is mentioned in a Hadith that to look at the face of an aalim is an act of Ibaadat. (Daylami – on the authority of Anas radiallahu anhu)
Rasulullah sallallahu alayhi wa sallam is reported to have said: “Allah be pleased with that man (and woman) who hears something from me and then conveys it to others exactly as he heard it. The reason is that often, the person who receives the message is more knowledgeable than the one who conveys it.” (Tirmidhi and Ibn Majah). How great a virtue has been attached to the knowledge of Deen that Rasulullah sallallahu alayhi wa sallam honoured the one who serves the Deen, especially the one who serves the science of Hadith by including him in his blessed dua. The Ulama have stated that through the learning and teaching of Hadith, if there was no other benefit apart from the blessings of this dua; even then one cannot afford to leave these blessings. In reality, great rewards apart from the blessings of this dua are found. O people! value this pious dua, seek knowledge of the Deen and there will be success in this world and in the hereafter.
