One night in the year 1986 I was sleeping adjacent to the Imam’s room at a time when the Imam had just been discharged from the hospital The Imam was still in a state of convalescing but all the same he would wake up to recite the optional night prayer. While performing ablutions at the stage of doing the ritual wiping of the feet, because it was difficult for him to bend down, he placed one hand on my shoulder for support and stated: “Worship God while you are still in your youth for when you become old like me, you shall no longer be able to do so.”
