Musannaf Ibn Abi Shaybah 37997 — The words of al-Hasan al-Basri

It is narrated from Amir bin Sa'd. He said: I met Sayyiduna Abu Ayyub al-Ansari (may Allah be pleased with him), and he said to me: Shall I not tell you to do what the Messenger of Allah (peace and blessings be upon him) told me to do? That I should say 'La hawla wa la quwwata illa billah' (There is no power and no strength except through Allah) abundantly, for it is one of the treasures of Paradise.
