Ahmed bin 'Ubda bin Musa أحمد بن عبدة بن موسى · Etiquette

"I met 'Umar bin Khattab and he said: 'Who are you?' I said: 'Masruq bin Adja'.' 'Umar said: 'I heard the Messenger of Allah(ﷺ) saying,"Ajda' is a devil."

"The Prophet (saas) heard me saying: 'La hawla wa la quwwata illa billah (there is no power and no strength except with Allah).' He said: 'O 'Abdullah bin Qais! Shall I not tell you of a word which is one of the treasures of Paradise?' I said: 'Yes, O Messenger of Allah.' He said: 'Say: La hawla wa la quwwata illa billah (There is no power and no strength except with Allah).'"
