Mukhtasar Muslim

It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) was on the mountain of Hira. The rock of the mountain shook, so the Messenger of Allah (peace and blessings of Allah be upon him) said, "Be still, O Hira! There is none upon you except a Prophet, a Siddiq, or a martyr." And with him (peace and blessings of Allah be upon him) were Sayyiduna Abu Bakr, Umar, Ali, Uthman, Talhah, and Zubair (may Allah be pleased with them). (The Prophet was the Messenger of Allah (peace and blessings of Allah be upon him) himself, the Siddiq was Sayyiduna Abu Bakr (may Allah be pleased with him), and the rest were all martyred, killed unjustly, including Sayyiduna Talhah and Zubair.)
