مسند أحمد

It was narrated that `Asim bin Kulaib said: I heard Abu Burdah say: I heard `Ali bin Abi Talib (رضي الله عنه) say: The Messenger of Allah (ﷺ) said: `Say: O Allah, I ask You for guidance and proper aim. When you ask for guidance, think of directions when travelling, and when you ask for proper aim, think of aiming an arrow.” And he forbade - or forbade me - to wear garments made from a blend of linen and silk, to use red saddle cloths, or to wear a ring on the forefinger or middle finger.
