Al-Husayn b. Ahmad b. Idris narrated to us. He said: My father narrated to us. He said: Ibrahim b. Hashim narrated to us from al-Hasan b. Mahbub from `Abd al-`Aziz b. al-`Abdi from `Abdullah b. Abi Ya`fur. He said: Abu `Abdillah al-Sadiq Ja`far b. Muhammad said:

O `Abdullah! When you pray an obligatory prayer, then pray it on-time in a meek way, fearing that you will never return to it again. Look to the place of your prostration (humble your sight), for if you knew who was to your right and to your left, you would have perfected your prayer. Know that you are before He who sees you while you cannot see Him.
