The prophet (SAW) said, "He who removes from a believer one of his difficulties of this world, Allah will remove one of his troubles on the Day of Resurrection; and he who finds relief for a hard-pressed person, Allah will cover up (his faults and sins) in this world and in the Hereafter. Allah supports His slave as long as the slave is supportive of his brother; and he who treads the path in search of knowledge, Allah makes that path easy, leading to Jannah for him; the people who assemble in one of the houses of Allah, reciting the Book of Allah, learning it and teaching, there descends upon them the tranquility, and mercy covers them, the angels flock around them, and Allah mentions them in the presence of those near Him; and he who lags behind in doing good deeds, his noble lineage will not make him go ahead."
