REWARD FOR FIGHTING A LITTLE H 1338 "A man in armor came to the Prophet, praise and peace be upon him, and asked, 'O Messenger of Allah, praise and peace be upon him, shall I go and fight; or shall I become a Muslim?" He answered, 'Become a Muslim and fight.' He became a Muslim, fought and was martyred, upon which the Messenger of Allah, praise and peace be upon him, said, 'He fought a little and was greatly rewarded.'" R 1338 Bukhari and Muslim with a chain up to Bra'a who related that the Messenger of Allah, praise and peace be upon him, said this.
1310- وعن البَراءِ رضي الله عنه ، قَالَ : أتَى النبيَّ صلى الله عليه وآله وسلم رَجُلٌ مُقَنَّعٌ بالحَدِيدِ ، فَقَالَ : يَا رسولَ اللهِ ، أُقَاتِلُ أَوْ أُسْلِمُ ؟ قَالَ : "أسْلِمْ ، ثُمَّ قَاتِلْ" . فَأسْلَمَ ، ثُمَّ قَاتَلَ فَقُتِلَ . فَقَالَ رسولُ اللهِ صلى الله عليه وآله وسلم : "عَمِلَ قَلِيلاً وَأُجِرَ كَثِيراً" متفقٌ عَلَيْهِ. وهذا لفظ البخاري .
