خُذْ مِنْ أَمْوَٰلِهِمْ صَدَقَةًۭ تُطَهِّرُهُمْ وَتُزَكِّيهِم بِهَا وَصَلِّ عَلَيْهِمْ ۖ إِنَّ صَلَوٰتَكَ سَكَنٌۭ لَّهُمْ ۗ وَٱللَّهُ سَمِيعٌ عَلِيمٌ ١٠٣
Take, [O Muhammad], from their wealth a charity by which you purify them and cause them increase, and invoke [ Allah’s blessing] upon them. Indeed, your invocations are reassurance for them. And Allah is Hearing and Knowing. Surah At-Tawbah (verse 103)
وَإِذْ أَخَذْنَا مِيثَٰقَ بَنِىٓ إِسْرَٰٓءِيلَ لَا تَعْبُدُونَ إِلَّا ٱللَّهَ وَبِٱلْوَٰلِدَيْنِ إِحْسَانًۭا وَذِى ٱلْقُرْبَىٰ وَٱلْيَتَٰمَىٰ وَٱلْمَسَٰكِينِ وَقُولُوا۟ لِلنَّاسِ حُسْنًۭا وَأَقِيمُوا۟ ٱلصَّلَوٰةَ وَءَاتُوا۟ ٱلزَّكَوٰةَ ثُمَّ تَوَلَّيْتُمْ إِلَّا قَلِيلًۭا مِّنكُمْ وَأَنتُم مُّعْرِضُونَ ٨٣
And when We took the covenant from the Children of Israel, , “Do not worship except Allah; and to parents do good and to relatives, orphans, and the needy. And speak to people good and establish prayer and give zakah.” Then you turned away, except a few of you, and you were refusing. Surah al-Baqarah (Verse 83)
From the above verses, it is clear that the obligation of the zakat and anyone who disbelieved or doubted its favors, then it was out of Islam. History has proven that Caliph Abu Bakr has been fighting against those who deny paying zakat. Those who are rich and well also need to realize that there is the right of the poor and needy in the property they possess.
