Sayyiduna Ali (may Allah be pleased with him) narrates that once the Prophet (peace and blessings be upon him) said to me: "Ali! I like for you what I like for myself, and I dislike for you what I dislike for myself. Do not recite the Noble Qur'an while in the state of bowing (ruku') or prostration (sajdah). Do not pray with your hair braided, for this is the way of Satan. Do not sit on your buttocks between the two prostrations. Do not play with pebbles during prayer. Do not spread your arms on the ground in prostration. Do not prompt the imam. Do not wear a gold ring. Do not wear silk clothing. And do not ride on a red saddlecloth."
