The Prophet ﷺ explained the reason for this, saying, “The flash of the swords over his head is trial enough.” Thus, both the martyr and the one standing guard are not approached in the grave by the two angels to question him; rather, he is safe from that interrogation. This is an immense distinction and a mighty reward.
As for the last hadith reported by Abu Hurayrah, it clearly proves the excellence of the one slain in Allah’s cause. For that reason the Prophet ﷺ swore that, were it not that he would burden the believers, he would never stay behind any expedition. Yet he sometimes remained behind to attend to the Muslims’ affairs, meet their needs, and spare them hardship. He also swore that he yearned to be killed in Allah’s cause, then brought back to life and killed again, and then revived and killed yet again. This shows the virtue of being slain for Allah’s sake; there is no doubt about it, and the Quran states it plainly:
“Do not think of those who have been killed in Allah’s cause as dead; rather, they are alive with their Lord, provided for, rejoicing in what Allah has granted them of His bounty, and delighted for those who have not yet joined them—that no fear shall be upon them, nor shall they grieve. They rejoice in favour and bounty from Allah, and Allah does not waste the reward of the believers.” ⦗Q 3:169-171⦘
This is an existence in the barzakh that we do not comprehend; it is not like our earthly life. Hence He said, “And do not say of those who are slain in Allah’s cause, ‘They are dead.’ Rather, they are alive, but you do not perceive it.” ⦗Q 2:154⦘. It is a life known only to Allah; if you were to open the grave you would see what appears to be a dead body, yet with Allah he is alive, provided for, eating from Paradise morning and evening.
We ask Allah, exalted be He, to grant us and you martyrdom in His cause, and to aid us and you in striving along His path.
