Prayer (Kitab Al-Salat): Details of Commencing Prayer

Dawud :: Book 3 : Hadith 944

Narrated AbuHurayrah:

The Prophet (peace_be_upon_him) said: Saying Tasbih applies to men during prayer and clapping applies to women. Anyone who makes a sign during his prayer, a sign which is intelligible by implication, should repeat it (i.e. his prayer).

(AbuDawud commented on the Hadith saying, this is a result of confusion.)
