It is narrated from Sayyiduna Jubair bin Mut’im that I heard the Prophet (peace and blessings be upon him) in the voluntary prayers recite three times: Allahu Akbar Kabira, three times: Walhamdulillahi Kathira, and three times: Subhanallahi Bukratan wa Aseela, and he would recite this supplication: O Allah! I seek refuge in You from the evil suggestions, spitting, and blowing of the accursed Satan. Amr says: By “evil suggestions” is meant that death which seizes the son of Adam, by “blowing” is meant arrogance, and by “spitting” is meant poetry.
