Safwan bin Ya'la bin Umayyah (may Allah have mercy on him) says: I came to Anbasah bin Abi Sufyan in Ta'if while he was close to death and was distressed by it. We said: Be of good cheer, O Abu Uthman! We have hope for you. He said: My sister, Sayyidah Umm Habibah (may Allah be pleased with her), the wife of the Prophet (peace and blessings be upon him), told me that the Prophet (peace and blessings be upon him) said: "Whoever prays twelve rak'ahs in the night or the day, besides the obligatory prayer, Allah will build for him a house in Paradise." Since I heard this, I have not abandoned them.
