The Excellence and Obligation of the Payment of Zakat
وَعَنْ اِبْنِ عُمَرَ رَضِيَ اَللَّهُ عَنْهُمَا، أَنَّ رَسُولَ اَللَّهِ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ قَالَ: بُنِيَ الإِسْلاَمُ عَلَى خَمْسٍ: شَهَادَةِ أَنْ لاَ إِلَهَ إِلاَّ اللَّهُ وَأَنَّ مُحَمَّدًا عَبْدُهُ وَرَسُولُهُ، إِقَامُ الصَّلاَةِ، وَإِيتَاءُ الزَّكَاةِ، وَحَجُّ الْبَيْتِ، وَصَوْمُ رمضان ((مُتَّفَقٌ عَلَيْهِ)) .
Ibn 'Umar (May Allah be pleased with them) reported: The Messenger of Allah (ﷺ) said, "(The structure of) Islam is built on five (pillars): Testification of 'La ilaha illallah' (none has the right to be worshipped but Allah), that Muhammad (ﷺ) is his slave and Messenger, the establishment of Salat, the payment of Zakat, the pilgrimage to the House of Allah (Ka'bah), and Saum during the month of Ramadan." [Al-Bukhari and Muslim].
