“Once I saw Ali ibn al-Husayn (a.s.) praying in the vicinity of al-Ka’bah in the night. He prolonged in standing so much so that he would lean on his right leg once and then on the left leg. Then I heard him saying with a crying voice, ‘O my Master, will You punish me while there is Your love in my heart? If You will do so You will be placing me together with the people with whom, just for Your sake, I had been enemies all along.’”
