Whoever glorifies Allah thirty-three times after every prayer, declares His greatness thirty-three times, and praises Him thirty-three times, then completes the hundred by saying, "There is no god but Allah alone, with no partner. His is the dominion, His is the praise, and He has power over all things," his sins will be forgiven, even if they were as much as the foam of the sea.
و حدثني عن مالك عن أبي عبيد مولى سليمان بن عبد الملك عن عطاء بن يزيد الليثي
من سبح دبر كل صلاة ثلاثا وثلاثين وكبر ثلاثا وثلاثين وحمد ثلاثا وثلاثين وختم المائة بلا إله إلا الله وحده لا شريك له له الملك وله الحمد وهو على كل شيء قدير غفرت ذنوبه ولو كانت مثل زبد البحر
