Al Mujadila Ayah 12

يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓاْ إِذَا نَـٰجَيْتُمُ ٱلرَّسُولَ فَقَدِّمُواْ بَيْنَ يَدَىْ نَجْوَٮٰكُمْ صَدَقَةً‌ۚ ذَٲلِكَ خَيْرٌ لَّكُمْ وَأَطْهَرُ‌ۚ فَإِن لَّمْ تَجِدُواْ فَإِنَّ ٱللَّهَ غَفُورٌ رَّحِيمٌ ١٢ O believers! When you consult the Messenger privately, give something in charity before your consultation. That is better and purer for you. But if you lack the means, then Allah is truly All-Forgiving, Most Merciful.
