I am faced with men who do not obey when I order and do not respond when I call them. May you have no father! (Woe to you!) What are you waiting for to rise for the cause of Allah? Does not faith join you together, or sense of shame rouse you? I stand among you shouting and I am calling you for help, but you do not listen to my word, and do not obey my orders, till circumstances show out their bad consequences.
