On the Prophet's forbearance, long-suffering and pardon

It is related that when the Prophet had his tooth broken and his face cut on the day of the Battle of Uhud, it was practically unbearable for his Companions. They said, "If only you would invoke a curse against them." He replied, "I was not sent to curse, but I was sent as a summoner and as a mercy. O Allah, guide my people for they do not know."
