Musannaf Ibn Abi Shaybah 37995 — The words of al-Hasan al-Basri

It is narrated from Amr bin Maymun that he heard Sayyiduna Abu Dharr (may Allah be pleased with him) say: I was walking behind the Prophet (peace and blessings be upon him) when he (peace and blessings be upon him) said: "Shall I not direct you to one of the treasures of Paradise?" I said: Certainly. He said: 'La hawla wa la quwwata illa billah' (There is no power and no strength except through Allah).
