Ali, Talhah, al-Zubayr and Sa'd (may Allah be pleased with them) were of the same age

It is narrated from Musa bin Talhah that he said: It used to be said about Sayyiduna Ali bin Abi Talib, Sayyiduna al-Zubayr, Sayyiduna Talhah bin Ubaydullah and Sayyiduna Sa'd bin Abi Waqqas (may Allah be pleased with them) that they were 'idhar 'amin wahid' (the peers of a single year). Ibrahim says: This means that they were all born in the same year.

Hisham bin Urwah narrates from his father that he related: Upon the death of Sayyiduna al-Zubayr bin al-Awwam (may Allah be pleased with him), his wife Atikah bint Zayd bin Amr bin Nufayl (may Allah be pleased with her) became his heir, and the amount of inheritance that came to her share reached eighty thousand dirhams. She composed these verses in elegy of Sayyiduna al-Zubayr (may Allah be pleased with him): "Ibn Jurmuz betrayed, on the day of the encounter, a brave horseman who never turned his back. O Amr! Had you alerted him, you would have found him such that neither his fingers nor his hand trembled (that is, he would have stood utterly firm). May your mother weep for you! Did you ever in the past overcome a horseman like him from among those who come and go morning and evening? How many hard battles did he face from which cowards like you could not turn him back! By Allah, who is your Lord! If you have killed a Muslim (unjustly), then the punishment of the deliberate killer has become binding upon you."
