At-Taubah - 9:71

وَالْمُؤْمِنُونَ وَالْمُؤْمِنَاتُ بَعْضُهُمْ أَوْلِيَاء بَعْضٍ يَأْمُرُونَ بِالْمَعْرُوفِ وَيَنْهَوْنَ عَنِ الْمُنكَرِ وَيُقِيمُونَ الصَّلاَةَ وَيُؤْتُونَ الزَّكَاةَ وَيُطِيعُونَ اللّهَ وَرَسُولَهُ أُوْلَـئِكَ سَيَرْحَمُهُمُ اللّهُ إِنَّ اللّهَ عَزِيزٌ حَكِيمٌ
[9:71]
And (as for) the believing men and the believing women, they are guardians of each other; they enjoin good and forbid evil and keep up prayer and pay the poor-rate, and obey Allah and His Messenger; (as for) these, Allah will show mercy to them; surely Allah is Mighty, Wise.
The Believers, men and women, are protectors one of another: they enjoin what is just, and forbid what is evil: they observe regular prayers, practise regular charity, and obey Allah and His Messenger. On them will Allah pour His mercy: for Allah is Exalted in power, Wise.
And the believers, men and women, are protecting friends one of another; they enjoin the right and forbid the wrong, and they establish worship and they pay the poor-due, and they obey Allah and His messenger. As for these, Allah will have mercy on them. Lo! Allah is Mighty, Wise.
