At-Tawbah 9:43

إِلَّا تَنصُرُوهُ فَقَدْ نَصَرَهُ اللَّهُ إِذْ أَخْرَجَهُ الَّذِينَ كَفَرُوا ثَانِيَ اثْنَيْنِ إِذْ هُمَا فِي الْغَارِ إِذْ يَقُولُ لِصَاحِبِهِ لَا تَحْزَنْ إِنَّ اللَّهَ مَعَنَا ۖ فَأَنزَلَ اللَّهُ سَكِينَتَهُ عَلَيْهِ وَأَيَّدَهُ بِجُنُودٍ لَّمْ تَرَوْهَا وَجَعَلَ كَلِمَةَ الَّذِينَ كَفَرُوا السُّفْلَىٰ ۗ وَكَلِمَةُ اللَّهِ هِيَ الْعُلْيَا ۗ وَاللَّهُ عَزِيزٌ حَكِيمٌ

If you do not aid the Prophet - Allah has already aided him when those who disbelieved had driven him out [of Makkah] as one of two, when they were in the cave and he said to his companion, "Do not grieve; indeed Allah is with us." And Allah sent down his tranquillity upon him and supported him with angels you did not see and made the word of those who disbelieved the lowest, while the word of Allah - that is the highest. And Allah is Exalted in Might and Wise.

انفِرُوا خِفَافًا وَثِقَالًا وَجَاهِدُوا بِأَمْوَالِكُمْ وَأَنفُسِكُمْ فِي سَبِيلِ اللَّهِ ۚ ذَٰلِكُمْ خَيْرٌ لَّكُمْ إِن كُنتُمْ تَعْلَمُونَ

Go forth, whether light or heavy, and strive with your wealth and your lives in the cause of Allah. That is better for you, if you only knew.

لَوْ كَانَ عَرَضًا قَرِيبًا وَسَفَرًا قَاصِدًا لَّاتَّبَعُوكَ وَلَـٰكِن بَعُدَتْ عَلَيْهِمُ الشُّقَّةُ ۚ وَسَيَحْلِفُونَ بِاللَّهِ لَوِ اسْتَطَعْنَا لَخَرَجْنَا مَعَكُمْ يُهْلِكُونَ أَنفُسَهُمْ وَاللَّهُ يَعْلَمُ إِنَّهُمْ لَكَاذِبُونَ

Had it been an easy gain and a moderate trip, the hypocrites would have followed you, but distant to them was the journey. And they will swear by Allah, "If we were able, we would have gone forth with you," destroying themselves [through false oaths], and Allah knows that indeed they are liars.

لَا يَسْتَأْذِنُكَ الَّذِينَ يُؤْمِنُونَ بِاللَّهِ وَالْيَوْمِ الْآخِرِ أَن يُجَاهِدُوا بِأَمْوَالِهِمْ وَأَنفُسِهِمْ ۗ وَاللَّهُ عَلِيمٌ بِالْمُتَّقِينَ

Those who believe in Allah and the Last Day would not ask permission of you to be excused from striving with their wealth and their lives. And Allah is Knowing of those who fear Him.

إِنَّمَا يَسْتَأْذِنُكَ الَّذِينَ لَا يُؤْمِنُونَ بِاللَّهِ وَالْيَوْمِ الْآخِرِ وَارْتَابَتْ قُلُوبُهُمْ فَهُمْ فِي رَيْبِهِمْ يَتَرَدَّدُونَ

Only those would ask permission of you who do not believe in Allah and the Last Day and whose hearts have doubted, and they, in their doubt, are hesitating.

وَلَوْ أَرَادُوا الْخُرُوجَ لَأَعَدُّوا لَهُ عُدَّةً وَلَـٰكِن كَرِهَ اللَّهُ انبِعَاثَهُمْ فَثَبَّطَهُمْ وَقِيلَ اقْعُدُوا مَعَ الْقَاعِدِينَ

And if they had intended to go forth, they would have prepared for it [some] preparation. But Allah disliked their being sent, so He kept them back, and they were told, "Remain [behind] with those who remain."
