(16) قُل لَّن يَنفَعَكُمُ الْفِرَارُ اِن فَرَرْتُم مِنَ الْمَوْتِ أَوِ الْقَتْلِ وَإِذاً لاَ تُمَتَّعُونَ إِلاَّ قَلِيلاً
16. "Say: 'Flight will never avail you if you flee from death or slaying, and in that case you will not be allowed to enjoy yourselves but a little'."
After that Allah divulged the intention of the hypocrites that their purpose was not the protection of their houses but they wanted to escape from the battle field, He answers them through two proofs: at first, He commands to His Messenger as follows:
slaying, and in that case you will not be allowed to enjoy
yourselves but a little'."
Supposing you succeed to escape, your position will be one of these two ones: either your life's final term has ended and your certain death has come, then wherever you are, death will seize you, even when you are at home beside your wife and your children, an incident from inside or outside puts an end to your life. And if your life's final term has not ended you will live in this world for a few days disgracefully and humiliatorily and you will be as a captive in the hand of enemies and then the divine punishment will seize you.
In fact, this statement is like what was revealed in the Battle of 'Uhud concerning another group of the slothful hypocrites, where the Qur'ān says: "… say: 'Even if you were in your own homes, those for whom slaughter was ordained would certainly have gone forth to their deathbeds; …", and they would be killed.
