مسند أحمد

It was narrated that ‘Ali (رضي الله عنه) said: The Messenger of Allah (ﷺ) said to me: `O ‘Ali, I love for you what I love for myself and l hate for you what I hate for myself. Do not recite Qur`an whilst bowing or whilst prostrating, do not pray with your hair twisted or braided and gathered up on the head, for that is the place where the Shaitan sits; do not sit like a dog between the two prostrations [putting the feet up and sitting on them]; do not play with the pebbles; do not lay your forearm along the ground; do not prompt the imam; do not wear gold rings; do not wear garments made from a blend of linen and silk, and do not ride on red saddle cloths.`
