It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him); he said: Sayyiduna Uthman bin Affan (may Allah be pleased with him) bought Paradise from the Prophet (peace and blessings be upon him) twice: once when he (peace and blessings be upon him) (encouraged the purchase of the well of) Bi'r Ma'unah, and the second time when he (peace and blessings be upon him) equipped the Army of Hardship (Jaysh al-Usrah). This hadith has a sahih chain, but the two Shaykhs did not record it.

It is narrated from Umayr bin Sa'id; he said: When Sayyiduna Ali (may Allah be pleased with him) intended to go to (the Battle of) Siffin in Syria, the people of the tribe of Nakha' gathered and came to the house of Malik al-Ashtar. Al-Ashtar asked: "Is there anyone in the house who is not from Nakha'?" The people said: "No." So he said: "This Ummah set upon its best man (Uthman (may Allah be pleased with him)) and killed him. We fought the people of Basra on the basis of a pledge of allegiance which we interpreted according to our own understanding, and now you are marching against a people over whom we hold no pledge of allegiance; so let every man consider where he is placing his sword." Although this hadith is (apparently) without a chain, in this place its chain is sahih.
