Narrated Abdullah ibn Khubayb: We went out one rainy and intensely dark night to look for the Messenger of Allah صلی اللہ علیہ وسلم to lead us in prayer, and when we found him, he asked: Have you prayed?, but I did not say anything. So he said: Say, but I did not say anything. He again said: Say, but I did not say anything. He then said: Say. So I said: What am I to say? He said: Say: Say, He is Allah, One, and al-Mu'awwadhatan thirty three times in the morning and evening; they will serve you for every purpose.
