وَلَقَدۡ كَانُواْ عَٰهَدُواْ ٱللَّهَ مِن قَبۡلُ لَا يُوَلُّونَ ٱلۡأَدۡبَٰرَۚ وَكَانَ عَهۡدُ ٱللَّهِ مَسۡـُٔولٗا
And indeed they had already made a covenant with Allah not to turn their backs, and a covenant with Allah must be answered for.
قُل لَّن يَنفَعَكُمُ ٱلۡفِرَارُ إِن فَرَرۡتُم مِّنَ ٱلۡمَوۡتِ أَوِ ٱلۡقَتۡلِ وَإِذٗا لَّا تُمَتَّعُونَ إِلَّا قَلِيلٗا
Say (O Muhammad SAW to these hypocrites who ask your permission to run away from you): "Flight will not avail you if you flee from death or killing, and then you will enjoy no more than a little while!"
قُلۡ مَن ذَا ٱلَّذِي يَعۡصِمُكُم مِّنَ ٱللَّهِ إِنۡ أَرَادَ بِكُمۡ سُوٓءًا أَوۡ أَرَادَ بِكُمۡ رَحۡمَةٗۚ وَلَا يَجِدُونَ لَهُم مِّن دُونِ ٱللَّهِ وَلِيّٗا وَلَا نَصِيرٗا
Say: "Who is he who can protect you from Allah if He intends to harm you, or intends mercy on you?" And they will not find, besides Allah, for themselves any Wali (protector, supporter, etc.) or any helper.
۞قَدۡ يَعۡلَمُ ٱللَّهُ ٱلۡمُعَوِّقِينَ مِنكُمۡ وَٱلۡقَآئِلِينَ لِإِخۡوَٰنِهِمۡ هَلُمَّ إِلَيۡنَاۖ وَلَا يَأۡتُونَ ٱلۡبَأۡسَ إِلَّا قَلِيلًا
Allah already knows those among you who keep back (men) from fighting in Allah's Cause, and those who say to their brethren "Come here towards us," while they (themselves) come not to the battle except a little.
