Musannaf Ibn Abi Shaybah 37998 — The words of al-Hasan al-Basri

It is narrated from Sayyiduna Zayd bin Thabit (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) used to say: "Shall I not direct you to one of the treasures of Paradise? Say 'La hawla wa la quwwata illa billah' (There is no power and no strength except through Allah) abundantly."
