The well was so deep the bottom has never been found, and the ring remained lost. After his death, the ring came down to Uthman, who accidentally dropped the ring into the well of Aris. Muhammad had a seal made of silver, with the words Muḥammad rasūl Allāh or 'Muhammad the Apostle of God.' The three words, on three lines, were on the ring, and Muhammad ordered that no duplicate was to be made.

Īccording to George Frederick Kunz, when Muhammad was about to send a letter to the Emperor Heraclius, he was told he needed a seal to be recognized as coming from him. Uthman is said to have made a replica of the seal, and this seal was supposedly found in the capture of Baghdad (1534) and brought to Istanbul.

According to Muslim historiographical tradition, Muhammad's original seal was inherited by Abu Bakr, Umar, and Uthman, but lost by Uthman in a well in Medina. The seal is a rectangular piece of red agate, about 1 cm (½') in length, inscribed with الله / محمد رسول (i.e., Allāh 'God' in the first line, and Muḥammad rasūl 'Muhammad, messenger' in the second). It has been used as recently as the 17th century to stamp documents. The seal itself is encased in crystal, approximately 3' × 4', with a border of ivory. Jean-Baptiste Tavernier in 1675 reported that the seal was kept in a small ebony box in a niche cut in the wall by the foot of a divan in the relic room at Topkapı.
