(36) باب مَسْأَلَةِ الشَّهَادَةِ .
It was narrated from Al-'Irbad bin Sariyah that the Messenger of Allah (ﷺ) said:
"The martyrs and those who dies in their beds referred a dispute to our Lord concerning those who dies of the plague. The martyrs said: 'Our brothers were killed as we were killed.' And those who dies in their beds said: 'Our brothers dies on their beds as we died.' Our Lord said: 'Look at their wounds; if their wounds; if their wounds are like the wounds of those who were killed then they are of them and belong with them.' And their wounds were like their (the martyrs') wounds."
