Mukhtasar Muslim

Narrated Abu Huraira (may Allah be pleased with him): The Messenger of Allah (peace and blessings of Allah be upon him) said: The truest statement uttered by a poet is the saying of Labid: "Beware! Everything besides Allah is vain." And Umayyah, the son of Abu Salt, was close to Islam (because his beliefs were good, although he was deprived of Islam).
