Abu Raja' al-Utaridi (may Allah have mercy on him) said: Sayyiduna Imran bin Husayn (may Allah be pleased with him) came out to us wearing a cloak of khazz (silk-wool), and said: The Messenger of Allah (peace and blessings be upon him) said: "When Allah bestows a blessing upon His servant, He loves to see the trace of His blessing upon him."
