33/46. Chapter:
It is recommended to seek Martyrdom in the Cause of Allah, Exalted is He.
Sahih Muslim
حَدَّثَنَا شَيْبَانُ بْنُ فَرُّوخَ، حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ، حَدَّثَنَا ثَابِتٌ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَنْ طَلَبَ الشَّهَادَةَ صَادِقًا أُعْطِيَهَا وَلَوْ لَمْ تُصِبْهُ " .
It has been narrated on the authority of Anas b. Malik that the Messenger of Allah (may peace he upon him) said: Who seeks martyrdom with sincerity shall get its reward, though he may not achieve it.
