The Repentance
قُلْ هَلْ تَرَبَّصُونَ بِنَآ إِلَّآ إِحْدَى ٱلْحُسْنَيَيْنِ ۖ وَنَحْنُ نَتَرَبَّصُ بِكُمْ أَن يُصِيبَكُمُ ٱللَّهُ بِعَذَابٍ مِّنْ عِندِهِۦٓ أَوْ بِأَيْدِينَا ۖ فَتَرَبَّصُوٓا۟ إِنَّا مَعَكُم مُّتَرَبِّصُونَ
Say, "Do you await for us except one of the two best things while we await for you that Allah will afflict you with punishment from Himself or at our hands? So wait; indeed we, along with you, are waiting."

إِن تُصِبْكَ حَسَنَةٌ تَسُؤْهُمْ ۖ وَإِن تُصِبْكَ مُصِيبَةٌ يَقُولُوا۟ قَدْ أَخَذْنَآ أَمْرَنَا مِن قَبْلُ وَيَتَوَلَّوا۟ وَّهُمْ فَرِحُونَ
If good befalls you, it distresses them; but if disaster strikes you, they say, "We took our matter [in hand] before," and turn away while they are rejoicing.
قُل لَّن يُصِيبَنَآ إِلَّا مَا كَتَبَ ٱللَّهُ لَنَا هُوَ مَوْلَىٰنَا ۚ وَعَلَى ٱللَّهِ فَلْيَتَوَكَّلِ ٱلْمُؤْمِنُونَ
Say, "Never will we be struck except by what Allah has decreed for us; He is our protector." And upon Allah let the believers rely.
قُلْ أَنفِقُوا۟ طَوْعًا أَوْ كَرْهًا لَّن يُتَقَبَّلَ مِنكُمْ ۖ إِنَّكُمْ كُنتُمْ قَوْمًا فَـٰسِقِينَ
Say, "Spend willingly or unwillingly; never will it be accepted from you. Indeed, you have been a defiantly disobedient people."
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.
