During Tasbih (saying: "Subhan Allah (Glory be to Allah)"), I sometimes think that I decrease or increase the needed count of Tasbih (35 times). Is this permissible?
When you doubt the count of Tasbih, you should act upon the lesser count. For instance, if you are unsure whether you reached thirty or thirty one times of saying Tasbih, you should regard it thirty times, for nonexistence is the origin until existence is proven.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
