﴿ ءَأَشْفَقْتُمْ أَن تُقَدِّمُوا۟ بَيْنَ يَدَىْ نَجْوَىٰكُمْ صَدَقَٰتٍۢ ۚ فَإِذْ لَمْ تَفْعَلُوا۟ وَتَابَ ٱللَّهُ عَلَيْكُمْ فَأَقِيمُوا۟ ٱلصَّلَوٰةَ وَءَاتُوا۟ ٱلزَّكَوٰةَ وَأَطِيعُوا۟ ٱللَّهَ وَرَسُولَهُۥ ۚ وَٱللَّهُ خَبِيرٌۢ بِمَا تَعْمَلُونَ ﴾

“Do you, perchance, fear lest [you may be sinning if] you cannot offer up anything in charity on the occasion of your consultation [with the Apostle]? But if you fail to do it [for lack of opportunity], and God turns unto you in His mercy, remain but con­stant in prayer and render [no more than] the purify­ing dues, and [thus] pay heed unto God and His Apostle: for God is fully aware of all that you do.”

When they stopped speaking with the Prophet (pbuh) because of the required almsgiving involved, Allah reproached them for doing so, saying: (Fear ye) are you miserly, O well off people, (to offer alms before your conference) to offer alms to the poor before speaking with the Prophet (pbuh)? (Then, when ye do it not) when you do not give alms (and Allah hath forgiven you) the question of giving alms, (establish worship) perform the five daily prayers (and pay the poor-due) from your wealth (and obey Allah) in that which He commands you (and His messenger) in that which he commands you. (And Allah is Aware of what ye do) whether it is good or evil. But no one gave alms for speaking with the Prophet (pbuh) except 'Ali Ibn Abi Talib who gave to alms a golden piece which he sold for ten silver pieces, and then asked the Prophet (pbuh) a question of ten words.
