Qur'an 58:12

يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا۟ إِذَا نَـٰجَيْتُمُ ٱلرَّسُولَ فَقَدِّمُوا۟ بَيْنَ يَدَىْ نَجْوَىٰكُمْ صَدَقَةً ۚ ذَٰلِكَ خَيْرٌ لَّكُمْ وَأَطْهَرُ ۚ فَإِن لَّمْ تَجِدُوا۟ فَإِنَّ ٱللَّهَ غَفُورٌ رَّحِيمٌ

“O you who have believed, when you [wish to] privately consult the Messenger, present before your consultation a charity. That is better for you and purer. But if you find not [the means] - then indeed, Allāh is Forgiving and Merciful.”
