وَقَالَتِ ٱلْيَهُودُ لَيْسَتِ ٱلنَّصَٰرَىٰ عَلَىٰ شَىْءٍۢ وَقَالَتِ ٱلنَّصَٰرَىٰ لَيْسَتِ ٱلْيَهُودُ عَلَىٰ شَىْءٍۢ وَهُمْ يَتْلُونَ ٱلْكِتَٰبَ ۗ كَذَٰلِكَ قَالَ ٱلَّذِينَ لَا يَعْلَمُونَ مِثْلَ قَوْلِهِمْ ۚ فَٱللَّهُ يَحْكُمُ بَيْنَهُمْ يَوْمَ ٱلْقِيَٰمَةِ فِيمَا كَانُوا۟ فِيهِ يَخْتَلِفُونَ
And the Jews say the Christians follow nothing (true), and the Christians say the Jews follow nothing (true); yet both are readers of the Scripture. Even thus speak those who know not. Allah will judge between them on the Day of Resurrection concerning that wherein they differ.
Surah Al-Baqara(2:113)
Sahih al-Bukhari
Obligatory Charity Tax (Zakat)
Chapter: To exhort one to give in charity
Narrated Ibn `Abbas:
The Prophet (ﷺ) went out for the `Id prayer on the `Id day and offered a two rak`at prayer; and he neither offered a prayer before it or after it. Then he went towards the women along with Bilal. He preached them and ordered them to give in charity. And some (amongst the women) started giving their forearm bangles and earrings.
