Charity does not reduce wealth. Because it gives blessings to your wealth. And it gives return that better than wealth.
In a hadith from Abu Hurairah (may Allah blesses him), that the Messenger of Allah (ﷺ) says,
مَا نَقَصَتْ صَدَقَةٌ مِنْ مَالٍ وَمَا زَادَ اللَّهُ عَبْدًا بِعَفْوٍ إِلاَّ عِزًّا وَمَا تَوَاضَعَ أَحَدٌ لِلَّهِ إِلاَّ رَفَعَهُ اللَّهُ
“Charity does not decrease wealth, no one forgives another but that Allah increases his honor, and no one humbles himself for the sake of Allah but that Allah raises his status” [Saheeh Muslim]
An Nawawi explains this hadits:
“The scholars say that what is meant here includes 2 things: First, means that his property is blessed and protected from harm. So the reduction of property (after charity) to be ‘even’ covered by an abstract blessing. This can be felt by the senses and habits. Second, if physically his wealth decreasing, then the reduction is ‘even’ covered by the reward from Allah obtained, and this reward is multiplied until it is many times over”.
