Narrated Aiyub:
Abu Qilaba said, "Malik bin Huwairith came to us and led us in the prayer in this mosque of ours and said, 'I lead you in prayer but I do not want to offer the prayer but just to show you how Allah's Apostle performed his prayers." I asked Abu Qilaba, "How was the prayer of Malik bin Huwairith?" He replied, "Like the prayer of this Sheikh of ours-- i.e. 'Amr bin Salima." That Sheikh used to pronounce the Takbir perfectly and when he raised his head from the second prostration he would sit for a while and then support himself on the ground and get up.
