Islam permits men to wear rings, so long as they are not made of gold. The Messenger of Allah (blessings and peace of Allah be upon him) had a ring made of silver. In this hadith, that is mentioned along with an explanation of some of the rulings on ‘Isha’ prayer and the virtue of waiting for the prayer. Humayd al-Tawil narrates that Anas ibn Malik (may Allah be pleased with him) was asked: Did the Messenger of Allah (blessings and peace of Allah be upon him) acquire a ring? He said: Yes. Then Anas (may Allah be pleased with him) stated that he saw the Messenger of Allah (blessings and peace of Allah be upon him) wearing his ring one night. The Prophet (blessings and peace of Allah be upon him) had delayed ‘Isha’ prayer on that night until halfway through the night, which is the best time [for ‘Isha’ prayer] for those who are able to do that. When the Prophet (blessings and peace of Allah be upon him) had finished the prayer at that time, he turned to face those who had prayed with him and said: Other people have prayed ‘Isha’, either at home or in a mosque where they usually pray in congregation, and gone to sleep, whilst you were gaining the reward of prayer throughout this time that you were waiting to pray, until half way through the night. So it is as if you were praying throughout the time that you were waiting. Then Anas (may Allah be pleased with him) said that he saw the glimmering of the silver of the ring of the Prophet (blessings and peace of Allah be upon him) as he was addressing them. The Prophet (blessings and peace of Allah be upon him) acquired a ring when he began to send letters to the kings and rulers, and he was told that they would not accept any letter that did not bear a seal. So he had a ring made of silver, on which were engraved the words “Muhammad Rasulullah (Muhammad the Messenger of Allah)”, as is narrated in al-Sahihayn. This hadith highlights the virtue of delaying ‘Isha’ prayer until almost half way through the night. It also highlights the virtue of waiting for prayer after prayer..
