Sayyiduna 'Uthman (radi Allahu anhu) belonged to the Ummayah tribe of the Quraish. He was a very rich cloth merchant. He was known as "Al Ghani" or "The Generous." His father's name was Affan and his mother was Urwa.
He accepted Islam at the invitation of Sayyiduna Abu Bakr (radi Allahu anhu) and migrated to Abyssinia with his wife, Sayyadah Ruqayyah (radi Allahu anha), who was also the daughter of Sayyiduna Rasulullah (sallal laahu alaihi wasallam).
During the Khilaafat of Sayyiduna 'Uthman (radi Allahu anhu), the rebellion in Azerbhaijaan and Armenia was silenced.
Sayyiduna Mu'awiyah (radi Allahu anhu), with the help of Sayyiduna Abi Sarah (radi Allahu anhu), captured Cyprus by naval attack and brought it under Islamic rule. Vast areas of North Africa including Tripoli, Tunisia and Morocco were also brought under the Islamic rule.
Sayyiduna 'Uthman (radi Allah anhu) was a very simple and very kind person. His simplicity and kindness did not alow him to take strong action against the trouble makers and rioters. Above all, because of his simple-mindedness, his administration was not as disciplined as it had been during the Khilaafat of Sayyiduna Umar (radi Allahu anhu).
A major achievement of Sayyiduna 'Uthman (radi Allahu anhu) was the duplication of the Holy Quran from the records kept by Sayyiduna Abu Bakr (radi Allahu anhu), who handed it to Sayyiduna Umar (radi Allahu anhu), who then handed it to his daughter, Sayyadah Hafsa (radi Allahu anha), the wife of Sayyiduna Rasulullah (sallal laahu alaihi wasallam).
Sayyiduna 'Uthman (radi Allahu anhu) made copies of the Holy Quran from the original and sent it to capitals such as Kufa, Damascus, Makkatul Mukarramah and Basrah, each accompanied by a Sahabi for the guidance of the readers.
