"If Allah wants to favor someone, He grants him comprehension (understanding) of this religion."
[Sahih Bukhari vol.1 # 71, Tirmidhi and Musnad Ahmad]
“It is only those who have knowledge amongst His slaves that fear Allah.”
[Soorah Al-Fatir (35): 28]
"Seek knowledge, because seeking it for the sake of Allah is a worship. And knowing it makes you more God-fearing; and searching for it is jihad, teaching it to those who do not know is charity, reviewing and learning it more is like tasbeeh. Through knowledge Allah will be known and worshipped. With the knowledge Allah will elevate people and make them leaders and imams, who will in turn guide other people."
[Fatawa Ibn Taymiyya vol.10, p.39]
"Whoever treads on a path in search of Islamic knowledge, Allah will ease the way to Paradise for him. The angels will lower their wings, pleased with this seeker of knowledge, and everyone in the heavens and on earth will ask forgiveness for the knowledgeable person, even the fish in the deepest of waters will ask for his forgiveness”
[Abu Dawud, Ibn Majah, Tirmidhi # 2835-sahih hadith]
“He whom death overtakes while he is engaged in acquiring knowledge with a view to reviving Islam with the help of it, there will be one degree between him and the Prophets in Paradise .”
