*The Messenger of Allah (peace and Allah's blessings be upon him) said: “When a person dies, his works end, except for three: ongoing charity, knowledge that is benefited from, and a righteous child who prays for him.” [Muslim, Tirmidhi]
* If anyone removes (one of the) anxieties of this world from a believer, Allah will remove (one of the) anxieties from him on the Day of Resurrection; if one smoothes the way for one who is destitute, Allah will smooth the way for him in this world and the next; and if anyone conceals the faults of a Muslim, Allah will conceal his faults in this world and the next. Allah helps a man as long as he helps his brother. If anyone pursues a path in search of knowledge Allah will thereby make easy for him a path to paradise.
* He who goes out in search of knowledge is in Allah's path till he returns.
* The search of knowledge is an obligation laid on every Muslim.
(Ibn Majah, Baihaqi).
