It is narrated from Sayyiduna Abu Umamah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "There are three things which, if I swore by them, I would be truthful, and a fourth which, if I swore by it too, I hope I would not be sinful: that Allah will not make the one who has a share in Islam like the one who has no share; that Allah will not take a servant under His protection in this world and then hand him over to someone else in the Hereafter; and that whoever takes a people under his patronage, Allah will raise him on the Day of Resurrection with them and among them. And the fourth is that Allah does not conceal the faults of a servant in this world except that He will conceal them on the Day of Resurrection as well."
