Messenger of Allah ﷺ said, "Give (in charity) and do not give reluctantly lest Allah should give you in a limited amount; and do not withhold your money lest Allah should withhold it from you."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ أَنْفِقِي وَلاَ تُحْصِي فَيُحْصِيَ اللَّهُ عَلَيْكِ وَلاَ تُوعِي فَيُوعِيَ اللَّهُ عَلَيْكِ
