Allah mentions here the valid excuses that permit one to stay away from fighting. He first mentions the excuses that remain with a person, the weakness in the body that disallows one from Jihad, such as blindness, limping, and so forth. He then mentions the excuses that are not permanent, such as an illness that would prevent one from fighting in the cause of Allah, or poverty that prevents preparing for Jihad. There is no sin in these cases if they remain behind, providing that when they remain behind, they do not spread malice or try to discourage Muslims from fighting, but all the while observing good behavior in this state, just as Allah said,

[مَا عَلَى الْمُحْسِنِينَ مِن سَبِيلٍ وَاللَّهُ غَفُورٌ رَّحِيمٌ]

(No means (of complaint) can there be against the doers of good. And Allah is Oft-Forgiving, Most Merciful.) Al-Awza`i said, "The people went out for the Istisqa' (rain) prayer. Bilal bin Sa`d stood up, praised Allah and thanked Him then said, `O those who are present! Do you concur that wrong has been done' They said, `Yes, by Allah!' He said, `O Allah! We hear your statement,

[مَا عَلَى الْمُحْسِنِينَ مِن سَبِيلٍ]

(No means (of complaint) can there be against the doers of good.) O Allah! We admit our errors, so forgive us and give us mercy and rain.' He then raised his hands and the people also raised their hands, and rain was sent down on them.'' Mujahid said about Allah's statement,

[وَلاَ عَلَى الَّذِينَ إِذَا مَآ أَتَوْكَ لِتَحْمِلَهُمْ]

(Nor (is there blame) on those who came to you to be provided with mounts) Mujahid said; "It was revealed about Bani Muqarrin from the tribe of Muzaynah. '' Ibn Abi Hatim recorded that Al-Hasan said that the Messenger of Allah said,

«لَقَدْ خَلَّفْتُمْ بِالْمَدِينَةِ أَقْوَامًا مَا أَنْفَقْتُمْ مِنْ نَفَقَةٍ وَلَا قَطَعْتُمْ وَادِيًا وَلَا نِلْتُمْ مِنْ عَدُوَ نَيْلًا إِلَّا وَقَدْ شَرَكُوكُمْ فِي الْأَجْر»

(Some people have remained behind you in Al-Madinah; and you never spent anything, crossed a valley, or afflicted hardship on an enemy, but they were sharing the reward with you.) He then recited the Ayah,

[وَلاَ عَلَى الَّذِينَ إِذَا مَآ أَتَوْكَ لِتَحْمِلَهُمْ قُلْتَ لاَ أَجِدُ مَآ أَحْمِلُكُمْ عَلَيْهِ]

(Nor (is there blame) on those who came to you to be provided with mounts, when you said: "I can find no mounts for you.'') This Hadith has a basis in the Two Sahihs from Anas, the Messenger of Allah said,

«إِنَّ بِالْمَدِينَةِ أَقْوَامًا مَا قَطَعْتُمْ وَادِيًا وَلَا سِرْتُمْ سَيْرًا إِلَّا وَهُمْ مَعَكُم»

(Some people have remained behind in Al-Madinah and you never crossed a valley or marched forth, but they were with you.) They said, "While they are still at Al-Madinah'' He said,

«نَعَمْ حَبَسَهُمُ الْعُذْر»

(Yes, as they have been held back by a (legal) excuse.) Then, Allah criticized those who seek permission to remain behind while they are rich, admonishing them for wanting to stay behind with women who remained in their homes,

[وَطَبَعَ اللَّهُ عَلَى قُلُوبِهِمْ فَهُمْ لاَ يَعْلَمُونَ]

(and Allah has sealed up their hearts, so that they know not (what they are losing).)

[يَعْتَذِرُونَ إِلَيْكُمْ إِذَا رَجَعْتُمْ إِلَيْهِمْ قُل لاَّ تَعْتَذِرُواْ لَن نُّؤْمِنَ لَكُمْ قَدْ نَبَّأَنَا اللَّهُ مِنْ أَخْبَارِكُمْ وَسَيَرَى اللَّهُ عَمَلَكُمْ وَرَسُولُهُ ثُمَّ تُرَدُّونَ إِلَى عَـلِمِ الْغَيْبِ وَالشَّهَـدَةِ فَيُنَبِّئُكُم بِمَا كُنتُمْ تَعْمَلُونَ - سَيَحْلِفُونَ بِاللَّهِ لَكُمْ إِذَا انْقَلَبْتُمْ إِلَيْهِمْ لِتُعْرِضُواْ عَنْهُمْ فَأَعْرِضُواْ عَنْهُمْ إِنَّهُمْ رِجْسٌ وَمَأْوَاهُمْ جَهَنَّمُ جَزَآءً بِمَا كَانُواْ يَكْسِبُونَ - يَحْلِفُونَ لَكُمْ لِتَرْضَوْاْ عَنْهُمْ فَإِن تَرْضَوْاْ عَنْهُمْ فَإِنَّ اللَّهَ لاَ يَرْضَى عَنِ الْقَوْمِ الْفَـسِقِينَ ]

(94. They (the hypocrites) will present their excuses to you (Muslims), when you return to them. Say "Present no excuses, we shall not believe you. Allah has already informed us of the news concerning you. Allah and His Messenger will observe your deeds. In the end you will be brought back to the All-Knower of the unseen and the seen, then He (Allah) will inform you of what you used to do.'') (95. They will swear by Allah to you (Muslims) when you return to them, that you may turn away from them. So turn away from them. Surely, they are Rijs (impure), and Hell is their dwelling place -- a recompense for that which they used to earn.) (96. They (the hypocrites) swear to you (Muslims) that you may be pleased with them, but if you are pleased with them, certainly Allah is not pleased with the people who are Fasiqin (rebellious).)
