It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: A Muslim is the brother of a Muslim; he does not oppress him nor does he abandon him helpless. Whoever strives to fulfill the need of his brother, Allah Almighty remains engaged in fulfilling his need. 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.

A companion of the Messenger narrates that the Holy Prophet, peace and blessings be upon him, said: Do good to your brothers, and in matters that overpower you, seek help from your brothers, and in matters that overpower them, help them.

Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates that two men came to the Noble Prophet (peace and blessings be upon him); they both had the same need. When one of them spoke, the Prophet (peace and blessings be upon him) noticed an unpleasant odor from his mouth and said: "Do you not use the miswak?" He replied: "Yes, I certainly do, but the fact is that I have not eaten food for three days." Then the Prophet (peace and blessings be upon him) instructed a person, so he took him and fulfilled his need.
