It was narrated from Ibn Jubair bin Mut’im that his father said:
“I saw the Messenger of Allah ﷺ when he started the prayer. He said: ‘Allahu Akbaru kabiran, Allahu Akbaru kabiran (Allah is the Most Great indeed),’ three times; ‘Al-hamdu Lillahi kathiran, al-hamdu Lillahi kathiran (Much praise is to Allah),’ three times; ‘Subhan Allahi bukratan wa asilan (Glory is to Allah morning and evening),’ three times; ‘Allahumma inni a’udhu bika minash-Shaitanir-rajim, min hamzihi wa nafkhihi wa nafthihi (O Allah, I seek refuge in You from the accursed Satan, from his madness, his poetry, and his pride).”
