It is narrated from Sayyiduna Abu Huraira (may Allah be pleased with him), he says: Whenever I used to go at the beginning of the prayer, I would find the Noble Prophet (peace and blessings be upon him) performing the prayer. So the Prophet (peace and blessings be upon him) performed the prayer and then said: Do you have pain in your stomach? I said: No. The Prophet (peace and blessings be upon him) said: Then stand up and perform the prayer, for there is healing in the prayer.
