It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) said: "Every Muslim is a brother to another Muslim; he does not oppress him nor does he hand him over to the enemy. Whoever is engaged in fulfilling his brother's needs, Allah Almighty is engaged in fulfilling his needs. Whoever removes a difficulty from a Muslim, Allah Almighty will remove his difficulty on the Day of Resurrection. And whoever conceals the faults of a Muslim, Allah Almighty will conceal his faults on the Day of Resurrection."
