Answer the following question briefly.
"Ali came out very slowly, turning after every few steps to gaze at the post office. His eyes were filled with tears of helplessness, for his patience was exhausted, even though he still had faith." Why were Ali's eyes filled with tears of helplessness? What had exhausted his patience but not his faith?
Ali was not keeping well for many days. His constant sickness deprived him of all his physical strength and stamina. He was also losing hold on his patience on account of his physical ailment and weakness. He knew that it was impossible for him now to make a daily visit to Post Office for getting the letter of his daughter. He also realized that his days were numbered, therefore his eyes were filled with tears. Though his physical infirmities and the shadow of approaching death exhausted his patience, yet they could not crush down his spirits and firm faith that one day his daughters letter would certainly come to him. His faith won because a letter came for him in the end.
