Abu Dawud Book 2, Hadith Number 944.

Narated By AbuHurayrah : The Prophet (PBUH) 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.)
