It is narrated from Sayyiduna Abu Qatadah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "The martyr does not feel the pain of being killed (in the path of Allah) except as much as one of you feels the pain of a pinch."
This hadith is narrated from Sayyiduna Abu Qatadah (may Allah be pleased with him) only with this chain, and Isa bin Hammad is alone in narrating it.
