What did Allah's Apostle (saw) do when he said, "Sami`a l-lahu liman hamidah"?
 Narrated Al-Bara:                     (and he was not a liar) When Allah's Apostle said, "Sami`a l-lahu liman hamidah" none of us bent his back (for prostration) till the Prophet prostrated and then we would prostrate after him.
