It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that the Holy Prophet (peace and blessings of Allah be upon him) said: Whoever relieves a Muslim of one of the worldly troubles, Allah will relieve him of one of the troubles of the Day of Resurrection. Whoever conceals the faults of a Muslim, Allah will conceal his faults in the Hereafter. And as long as a servant remains engaged in helping his brother, Allah Almighty remains engaged in helping that servant.
