Paradise shines for Uthman (may Allah be pleased with him)

It is narrated from Sayyiduna Sahl bin Sa'd (may Allah be pleased with him) that a man asked the Prophet (peace and blessings be upon him): "Is there the flash of lightning in Paradise?" He (peace and blessings be upon him) said: "Yes. By the One in whose hand is my soul! Indeed, when Uthman moves from one dwelling to another, Paradise lights up (with his light)."
If al-Husayn bin Ubaydullah has preserved it (in this way) from Abd al-Aziz bin Abi Hazim, then it is sahih on the condition of the two Shaykhs.

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that when Sayyiduna Uthman (may Allah be pleased with him) was besieged (in his house), he sought permission to speak. On that occasion Sayyiduna Abu Hurayrah (may Allah be pleased with him) said: I heard the Messenger of Allah (peace and blessings be upon him) say: "Soon there will be tribulation and discord (or he said: discord and tribulation)." We said: "O Messenger of Allah (peace and blessings be upon him)! Then what do you command us to do at that time?" He (peace and blessings be upon him) said: "Hold fast to the leader (amir) and his companions," and he (peace and blessings be upon him) pointed towards Sayyiduna Uthman (may Allah be pleased with him).
This hadith has a sahih chain, but the two Shaykhs did not record it.
