Surat At-Tawbah (42-43)

{لَوْ كَانَ عَرَضاً قَرِيباً وَسَفَراً قَاصِداً لاَّتَّبَعُوكَ وَلَـكِن بَعُدَتْ عَلَيْهِمُ الشُّقَّةُ وَسَيَحْلِفُونَ بِاللّهِ لَوِ اسْتَطَعْنَا لَخَرَجْنَا مَعَكُمْ يُهْلِكُونَ أَنفُسَهُمْ وَاللّهُ يَعْلَمُ إِنَّهُمْ لَكَاذِبُونَ} [التوبة: 42]

42- O Prophet, if your call to them was for an easy booty or for a short-distant journey, the people who sought your permission to stay would go out with you, but when the distance was so far [to the Levant], they sought your permission to stay.

Those who lagged behind shall swear falsely by Allah saying: If we could go with you, we would do it. However, they destroy themselves with this false oath which shall cast them into torment; and Allah knows they are liars.

{عَفَا اللّهُ عَنكَ لِمَ أَذِنتَ لَهُمْ حَتَّى يَتَبَيَّنَ لَكَ الَّذِينَ صَدَقُواْ وَتَعْلَمَ الْكَاذِبِينَ} [التوبة: 43]

43- O Prophet, may Allah forgive you! Why did you give them permission to lag behind Jihad when they were able to go?! Would you wait and make sure of their conditions to know the truthful from the liar?
