Al-Hadeed 58:12

يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا۟ إِذَا نَٰجَيْتُمُ ٱلرَّسُولَ فَقَدِّمُوا۟ بَيْنَ يَدَىْ نَجْوَىٰكُمْ صَدَقَةًۭ ۚ ذَٰلِكَ خَيْرٌۭ لَّكُمْ وَأَطْهَرُ ۚ فَإِن لَّمْ تَجِدُوا۟ فَإِنَّ ٱللَّهَ غَفُورٌۭ رَّحِيمٌ

O ye who believe! When ye consult the Messenger in private, spend something in charity before your private consultation. That will be best for you, and most conducive to purity (of conduct). But if ye find not (the wherewithal), Allah is Oft-Forgiving, Most Merciful.
