It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that whenever I went out at noon, I found the Holy Prophet (peace and blessings be upon him) performing prayer. (One day when I was present) the Holy Prophet (peace and blessings be upon him), after finishing the prayer, asked in Persian, "Do you have pain in your stomach?" I replied, "No." He said, "Perform the prayer standing, for there is healing in the prayer."
