Abdullah bin Umar reported,

He informed him that the Messenger of Allah ﷺ said, "A Muslim is the brother of another Muslim. He does not wrong him, nor does he hand him over to an enemy. Whoever attends to the needs of his brother, Allah will attend to his needs. Whoever relieves a Muslim of a hardship, Allah will relieve him of one of the hardships of the Day of Resurrection. Whoever conceals the faults of a Muslim, Allah will conceal his faults on the Day of Resurrection."
