۞ وَلَقَدْ أَخَذَ ٱللَّهُ مِيثَٰقَ بَنِىٓ إِسْرَٰٓءِيلَ وَبَعَثْنَا مِنْهُمُ ٱثْنَىْ عَشَرَ نَقِيبًۭا ۖ وَقَالَ ٱللَّهُ إِنِّى مَعَكُمْ ۖ لَئِنْ أَقَمْتُمُ ٱلصَّلَوٰةَ وَءَاتَيْتُمُ ٱلزَّكَوٰةَ وَءَامَنتُم بِرُسُلِى وَعَزَّرْتُمُوهُمْ وَأَقْرَضْتُمُ ٱللَّهَ قَرْضًا حَسَنًۭا لَّأُكَفِّرَنَّ عَنكُمْ سَيِّـَٔاتِكُمْ وَلَأُدْخِلَنَّكُمْ جَنَّٰتٍۢ تَجْرِى مِن تَحْتِهَا ٱلْأَنْهَٰرُ ۚ فَمَن كَفَرَ بَعْدَ ذَٰلِكَ مِنكُمْ فَقَدْ ضَلَّ سَوَآءَ ٱلسَّبِيلِ
Allah made a covenant of old with the Children of Israel and We raised among them twelve chieftains, and Allah said: Lo! I am with you. If ye establish worship and pay the poor-due, and believe in My messengers and support them, and lend unto Allah a kindly loan, surely I shall remit your sins, and surely I shall bring you into Gardens underneath which rivers flow. Whoso among you disbelieveth after this will go astray from a plain road.
Surah Al-Maaida(5:12)
