يا أَيُّهَا الَّذينَ آمَنوا إِذا ناجَيتُمُ الرَّسولَ فَقَدِّموا بَينَ يَدَي نَجواكُم صَدَقَةً ۚ ذٰلِكَ خَيرٌ لَكُم وَأَطهَرُ ۚ فَإِن لَم تَجِدوا فَإِنَّ اللَّهَ غَفورٌ رَحيمٌ

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, Allah is Forgiving and Merciful.
