morning comes, ‘There is no god but Allah alone, with no partner. His is the dominion and His is all praise, and He has power over all things,’ ten times, will have ten good deeds recorded for him, ten sins erased, and his rank raised by ten degrees. These words will earn him the equivalent of freeing four slaves and protect him from Satan until evening. Whoever says them after completing the Maghrib prayer will receive the same until morning.”
The Prophet’s words, peace and blessings be upon him, concerning the opening of prayer have already been cited: “‘Allah is the Greatest’ ten times, ‘All praise is due to Allah’ ten times, ‘Glory be to Allah’ ten times, and ‘There is no god but Allah’ ten times. He asks Allah for forgiveness ten times and says, ‘O Allah, forgive me, guide me, and provide for me,’ ten times, and seeks refuge from the distress of the Day of Resurrection ten times.”
Thus, ten repetitions occur frequently in remembrances and supplications. As for eleven, this number is never mentioned in any of them except in some chains of transmission of the previously cited hadith of Abū Hurayrah. Allah (1) knows best.
