Abu Shaykh Hanai says: I was once sitting with Muawiyah (may Allah be pleased with him) in a gathering of some of the noble Companions (may Allah be pleased with them). Muawiyah (may Allah be pleased with him) asked them: I ask you by Allah’s oath, do you know that the Prophet (peace and blessings be upon him) forbade wearing silk? They replied: Yes! Muawiyah (may Allah be pleased with him) said: I also bear witness to this. Then he said: I ask you by oath, do you know that the Prophet (peace and blessings be upon him) forbade men from wearing gold except a little? They replied: Yes. Muawiyah (may Allah be pleased with him) said: I also bear witness to this. Then he said: I ask you by Allah’s oath, do you know that the Prophet (peace and blessings be upon him) forbade riding on a leopard? They replied: Yes! He said: I also bear witness to this. Then he said: I ask you by Allah’s oath, do you know that the Prophet (peace and blessings be upon him) forbade drinking water from silver vessels? They replied: Yes! He said: I also bear witness to this. Then he said: I ask you by Allah’s oath, do you know that the Prophet (peace and blessings be upon him) forbade combining Hajj and Umrah in one journey? They replied: We do not know this matter. Muawiyah (may Allah be pleased with him) said: This matter is also established and is with the previous matters.
