Tasbih

Tasbih (تسبيح) is a form of dhikr that involves the repetitive utterances of short sentences glorifying God. The term can also be used loosely to refer to any kind of dhikr.[citation needed] To keep track of counting either the phalanges of the right hand or a misbaha is used.

Subhan'allah (سبحان الله) (Glory be to Allah) – repeated 33 times.
Alhamdulillah (الحمد لله) (Gratitude be to Allah) – repeated 33 times.
Allahu akbar (الله أكبر) (God is the greatest) – repeated 33 times.


The most cited Hadiths in support of the practice are the following:

من سبح لله في دبر كل صلاة ، ثلاثاً و ثلاثين وحمد الله ثلاثاً وثلاثين وكبر ثلاثاً وثلاثين تكبيرة ، وقال تمام المئة ، لا إله إلا الله وحده لا شريك له ، له الملك وله الحمد وهو على كل شيء قدير ، غفرت له خطاياه وإن كانت مثل زبد البحر ) – He who said Subhan'allah (Glory be to Allah) at the rear of each prayer thirty three times and thanked God thirty three times and performed takbir (Said Allahu Akbar: Greatest is Allah) thirty three times, and said there is no god but Allah nor he has a partner, his is the Mulk (All that is) and to him is Gratitude and he capable of everything, his transgressions would be forgiven even if they were as much as sea froth).
