Al-Mujadila 58:12
يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا۟ إِذَا نَـٰجَيْتُمُ ٱلرَّسُولَ فَقَدِّمُوا۟ بَيْنَ يَدَىْ نَجْوَىٰكُمْ صَدَقَةً ۚ ذَٰلِكَ خَيْرٌ لَّكُمْ وَأَطْهَرُ ۚ فَإِن لَّمْ تَجِدُوا۟ فَإِنَّ ٱللَّهَ غَفُورٌ رَّحِيمٌ
Ya ayyuha allatheena amanooitha najaytumu arrasoola faqaddimoo baynayaday najwakum sadaqatan thalika khayrunlakum waatharu fa-in lam tajidoo fa-inna Allahaghafoorun raheem
