Verse of the Holy Quran
وَالْمُؤْمِنُونَ وَالْمُؤْمِنَاتُ بَعْضُهُمْ اَوْلِيَٓاءُ بَعْضٍۢ يَأْمُرُونَ بِالْمَعْرُوفِ وَيَنْهَوْنَ عَنِ الْمُنْكَرِ وَيُق۪يمُونَ الصَّلٰوةَ وَيُؤْتُونَ الزَّكٰوةَ وَيُط۪يعُونَ اللّٰهَ وَرَسُولَهُۜ اُو۬لٰٓئِكَ سَيَرْحَمُهُمُ اللّٰهُۜ اِنَّ اللّٰهَ عَز۪يزٌ حَك۪يمٌ
All believers, men and women, are friends and protectors of each other. They enjoin good, forbid evil, establish prayer, give alms, and obey Allah and His Messenger. Allah will judge them with His mercy. Because Allah is Almighty and Wise.
