انْفِرُوا خِفَافًا وَثِقَالًا وَجَاهِدُوا بِأَمْوَالِكُمْ وَأَنْفُسِكُمْ فِي سَبِيلِ اللَّهِ ۚ ذَٰلِكُمْ خَيْرٌ لَكُمْ إِنْ كُنْتُمْ تَعْلَمُونَ ٤١
Go ye forth, (whether equipped) lightly or heavily, and strive and struggle, with your goods and your persons, in the cause of Allah. That is best for you, if ye (but) knew.
لَوْ كَانَ عَرَضًا قَرِيبًا وَسَفَرًا قَاصِدًا لَاتَّبَعُوكَ وَلَٰكِنْ بَعُدَتْ عَلَيْهِمُ الشُّقَّةُ ۚ وَسَيَحْلِفُونَ بِاللَّهِ لَوِ اسْتَطَعْنَا لَخَرَجْنَا مَعَكُمْ يُهْلِكُونَ أَنْفُسَهُمْ وَاللَّهُ يَعْلَمُ إِنَّهُمْ لَكَاذِبُونَ ٤٢
If there had been immediate gain (in sight), and the journey easy, they would (all) without doubt have followed thee, but the distance was long, (and weighed) on them. They would indeed swear by Allah, "If we only could, we should certainly have come out with you": They would destroy their own souls; for Allah doth know that they are certainly lying.
عَفَا اللَّهُ عَنْكَ لِمَ أَذِنْتَ لَهُمْ حَتَّىٰ يَتَبَيَّنَ لَكَ الَّذِينَ صَدَقُوا وَتَعْلَمَ الْكَاذِبِينَ ٤٣
Allah give thee grace! why didst thou grant them until those who told the truth were seen by thee in a clear light, and thou hadst proved the liars?
لَا يَسْتَأْذِنُكَ الَّذِينَ يُؤْمِنُونَ بِاللَّهِ وَالْيَوْمِ الْآخِرِ أَنْ يُجَاهِدُوا بِأَمْوَالِهِمْ وَأَنْفُسِهِمْ ۗ وَاللَّهُ عَلِيمٌ بِالْمُتَّقِينَ ٤٤
Those who believe in Allah and the Last Day ask thee for no exemption from fighting with their goods and persons. And Allah knoweth well those who do their duty.
إِنَّمَا يَسْتَأْذِنُكَ الَّذِينَ لَا يُؤْمِنُونَ بِاللَّهِ وَالْيَوْمِ الْآخِرِ وَارْتَابَتْ قُلُوبُهُمْ فَهُمْ فِي رَيْبِهِمْ يَتَرَدَّدُونَ ٤٥
Only those ask thee for exemption who believe not in Allah and the Last Day, and whose hearts are in doubt, so that they are tossed in their doubts to and fro.
