Whoever conceals (the faults of) a Muslim, Allah will conceal his faults in this world and the Hereafter. Whoever makes things easy for a person in difficulty and distress, Allah will make things easy for him in this world and the Hereafter. Allah continues to help His servant as long as the servant is engaged in helping his brother. Whoever treads a path in search of knowledge, Allah will make easy for him a path to Paradise because of it. Whenever people gather in one of the houses of Allah, reciting the Book of Allah and teaching it to one another, tranquility descends upon them, mercy covers them, the angels surround them, and Allah mentions them among those who are with Him. And whoever is held back by his deeds, his lineage will not push him forward.

Whoever removes a difficulty from a Muslim, Allah Almighty will remove one of his difficulties from the difficulties of the Day of Resurrection. And whoever conceals (the faults of) a Muslim, Allah Almighty will conceal him on the Day of Resurrection.
