It is narrated from Sayyiduna Mu'adh bin Anas al-Juhani (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Whoever suppresses his anger while he has the power to act upon it, Allah Almighty will give him the choice among the wide-eyed houris (hur al-'in) on the Day of Resurrection. And whoever gives up a beautiful garment while being able to wear it, Allah Almighty will clothe him with the cloak of faith. And whoever arranges the marriage of a slave for the sake of Allah, Allah Almighty will place the crown of kingship upon his head."
