I will lead you in prayer; although I do not intend to pray, it is just to show you how I witnessed the Messenger of Allah pray

Abu Qilābah said that Mālik ibn al-Huwayrith, who was one of the Companions, approached them in their mosque saying that he had come to them to lead them in prayer, with the intention of teaching them practically how the Messenger (may Allah's peace and blessings be upon him) prayed. He did that because seeing a practical demonstration of something is easy to understand and lasts a long time in people’s memories. The narrator asked Abu Qilābah how Mālik ibn al-Huwayrith prayed. He replied telling him that it was the same way as their sheikh, Abu Zayd ‘Amr ibn Salāmah al-Jarmi, prayed. The sheikh would sit briefly when he raised his head from prostration and before standing up.
