Musnad Ahmad 1013:6

Sufyan narrated to us, from Abu Hazim, who heard Sahl ibn Sa'd, from the Prophet, peace and blessings be upon him, who said: "Whoever is struck by something in his prayer, let him say: 'Subhan Allah' (Glory be to Allah). Indeed, clapping is for women, and tasbih (saying Subhan Allah) is for men."
