Sayyiduna Abu Raja’ Ataridi says: Sayyiduna Imran bin Husain (may Allah be pleased with him) came before us and he was wearing a cloak made of wool and silk. We had never seen such a cloak before or after that. The Noble Prophet (peace and blessings be upon him) saw him and said: Whoever Allah Almighty has bestowed blessings upon, Allah also likes that the effect of His blessing be seen on His creation.
