وَمَا مَنَعَهُمْ أَن تُقْبَلَ مِنْهُمْ نَفَقَـٰتُهُمْ إِلَّآ أَنَّهُمْ كَفَرُوا۟ بِٱللَّهِ وَبِرَسُولِهِۦ وَلَا يَأْتُونَ ٱلصَّلَوٰةَ إِلَّا وَهُمْ كُسَالَىٰ وَلَا يُنفِقُونَ إِلَّا وَهُمْ كَـٰرِهُونَ
And what prevents their expenditures from being accepted from them but that they have disbelieved in Allah and in His Messenger and that they come not to prayer except while they are lazy and that they do not spend except while they are unwilling.
فَلَا تُعْجِبْكَ أَمْوَٰلُهُمْ وَلَآ أَوْلَـٰدُهُمْ ۚ إِنَّمَا يُرِيدُ ٱللَّهُ لِيُعَذِّبَهُم بِهَا فِى ٱلْحَيَوٰةِ ٱلدُّنْيَا وَتَزْهَقَ أَنفُسُهُمْ وَهُمْ كَـٰفِرُونَ
So let not their wealth or their children impress you. Allah only intends to punish them through them in worldly life and that their souls should depart [at death] while they are disbelievers.
لَوْ يَجِدُونَ مَلْجَـًٔا أَوْ مَغَـٰرَٰتٍ أَوْ مُدَّخَلًا لَّوَلَّوْا۟ إِلَيْهِ وَهُمْ يَجْمَحُونَ
If they could find a refuge or some caves or any place to enter [and hide], they would turn to it while they run heedlessly.
وَمِنْهُم مَّن يَلْمِزُكَ فِى ٱلصَّدَقَـٰتِ فَإِنْ أُعْطُوا۟ مِنْهَا رَضُوا۟ وَإِن لَّمْ يُعْطَوْا۟ مِنْهَآ إِذَا هُمْ يَسْخَطُونَ
And among them are some who criticize you concerning the [distribution of] charities. If they are given from them, they approve; but if they are not given from them, at once they become angry.
