The engraving on the ring of Uthman (may Allah be pleased with him) was: O Allah, let me live happy and die a martyr

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that he was asked about Sayyiduna Uthman (may Allah be pleased with him): what was engraved on the stone of his ring? He said: Because of the sincerity of his intention, these words were inscribed on the stone of his ring: 'Allahumma ahyini sa'idan wa amitni shahidan' (O Allah, grant me a life of felicity and grant me the death of a martyr). So by Allah! He lived with felicity and died the death of a martyr.

It is narrated from Husayn al-Harithi; he said: Sayyiduna Ali bin Abi Talib (may Allah be pleased with him) came to visit Sayyiduna Zayd bin Arqam (may Allah be pleased with him) in his illness, while some people were present there. Sayyiduna Ali (may Allah be pleased with him) said: "Sit calmly and keep quiet; by Allah! Whatever you ask me about, I will (surely) tell you." Zayd (may Allah be pleased with him) said: "I ask you by Allah, did you kill Uthman?" At this Sayyiduna Ali (may Allah be pleased with him) lowered his head for a while, then said: "By the One who split the seed and created the soul, I neither killed him nor ordered his killing."

Harun says: Abu Usamah narrated to us from Zuhayr, from Kinanah; he said: I saw Sayyiduna Hasan bin Ali (may Allah be pleased with them both) being carried out wounded from the house of Sayyiduna Uthman (may Allah be pleased with him).
