Æeaving the recitation of Bismillah-ir-Rahman-ir-Rahim in audible voice in the prayer

 279. Anas reported: I performed prayer along with the Messenger of Allah salla alayhi wa sallam and with Abu Bakr, ´Umar and ´Uthman, but I never heard anyone of them reciting Bismillah-ir-Rahman-ir-Rahim (In the Name of Allah, the Most Gracious and the Most Merciful) in audible voice.
