Muhammad ibn Ahmad ibn Yahya, from Muhammad ibn ‘Isa, from Yusuf ibn ‘Aqil, from Muhammad ibn Qays, from Abu Ja‘far عليه السلام (peace be upon him), who said: (imam عليه السلام said) “Commander of the Faithful, (Imam Ali Ibn Abi Talib عليه السلام), peace be upon him, when He عليه السلام prayed, would recite silently in the first two rak‘ahs of his Dhuhr prayer, and He عليه السلام would perform ‘tasbih’ (glorification) in the last two rak‘ahs of his Dhuhr prayer, similar to what He عليه السلام did in the Isha prayer. And He عليه السلام would recite silently in the first two rak‘ahs of his ‘Asr prayer, and He عليه السلام would perform ‘tasbih’ in the last two rak‘ahs similar to what He عليه السلام did in the Isha prayer. And He عليه السلام used to say: ‘The beginning of the prayer of one of you is the bowing.’”
