Abu Qilabah (may Allah have mercy on him) says: Malik bin Huwairith (may Allah be pleased with him) came to us, prayed in our mosque, and said: By Allah, I will lead you in prayer, and my intention is not for prayer, but I want to show you the way of prayer in which I saw the Prophet (peace and blessings of Allah be upon him) praying. Then he mentioned the manner of standing after the first rak'ah. The narrator says: I asked, "How did you pray?" He replied, "Like this prayer of mine."
