Surat At-Tawbah (90-92)

{وَجَاء الْمُعَذِّرُونَ مِنَ الأَعْرَابِ لِيُؤْذَنَ لَهُمْ وَقَعَدَ الَّذِينَ كَذَبُواْ اللّهَ وَرَسُولَهُ سَيُصِيبُ الَّذِينَ كَفَرُواْ مِنْهُمْ عَذَابٌ أَلِيمٌ} [التوبة: 90]

90- The people who lagged behind Jihad from the people of Medina and the areas around it came to ask for permission not to participate in the battle. There are other type of people who were hypocrites who lagged behind Jihad without seeking permission. Their action was a proof that they disbelieved in Allah and lied to the Prophet (peace be upon him), accordingly they shall have the painful punishment of disbelievers.

{لَّيْسَ عَلَى الضُّعَفَاء وَلاَ عَلَى الْمَرْضَى وَلاَ عَلَى الَّذِينَ لاَ يَجِدُونَ مَا يُنفِقُونَ حَرَجٌ إِذَا نَصَحُواْ لِلّهِ وَرَسُولِهِ مَا عَلَى الْمُحْسِنِينَ مِن سَبِيلٍ وَاللّهُ غَفُورٌ رَّحِيمٌ} [التوبة: 91]

91- There is no sin in lagging behind Jihad for weak and sick people who could not participate in Jihad as well as the poor who could not find the equipment of war.

There is no sin on them if they can give advices, had strong faith, kept the promise of Allah, and did not spread rumors and fear among people.

So, there is no sin on those who had done well, feared Allah, believed, and advised fighters any harm or sin; and Allah forgives those people with His Mercy.

{وَلاَ عَلَى الَّذِينَ إِذَا مَا أَتَوْكَ لِتَحْمِلَهُمْ قُلْتَ لاَ أَجِدُ مَا أَحْمِلُكُمْ عَلَيْهِ تَوَلَّواْ وَّأَعْيُنُهُمْ تَفِيضُ مِنَ الدَّمْعِ حَزَناً أَلاَّ يَجِدُواْ مَا يُنفِقُونَ} [التوبة: 92]

92- Moreover, there is no blame for those who came to you to ask you for a mount to participate in Jihad and you said to them: I cannot find anything to carry you on. Then they returned homes sad and crying because they could not find money to buy the equipment of Jihad.
