The martyr feels nothing from the agony of death except as one of you feels from the sting of an ant
Good hadithعن أبي هريرة رضي الله عنه قال: قال رسول الله صلى الله عليه وسلم : «مَا يَجِدُ الشَّهيد من مَسِّ القتل إلا كما يَجِدُ أَحَدُكُمْ من مَسِّ القَرْصَةِ».
Abu Hurayrah (may Allah be pleased with him) reported that the Messenger of Allah (may Allah’s peace and blessings be upon him) said: “The martyr feels nothing from the agony of death except as one of you feels from the sting of an ant.”
Explanation
Explanation: When a person is martyred in the cause of Allah, what he suffers from the agony or pain of death is similar to the pain that we feel from the sting an ant. This means that the martyr does not suffer the throes and stupors of death the way other people do; rather, the greatest pain he suffers and feels at the time of his death is similar to the quick pain that we feel from the bite of an ant. This is part of the favor of Allah, the Almighty, upon the martyr. He sacrificed his life for the sake of Allah, considering it a small price to pay, and thus Allah alleviated the pain of death from him.
