Abu Hurairah reported the Apostle of Allaah(ﷺ) as saying “Whatever town you come to and stay in , your portion is in it, but whatever town disobeys Allaah and His Apostle a fifth of it goes to Allaah and His Apostle and what remains is yours.”
حَدَّثَنَا أَحْمَدُ بْنُ حَنْبَلٍ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، حَدَّثَنَا مَعْمَرٌ، عَنْ هَمَّامِ بْنِ مُنَبِّهٍ، قَالَ هَذَا مَا حَدَّثَنَا بِهِ أَبُو هُرَيْرَةَ، عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم وَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " أَيُّمَا قَرْيَةٍ أَتَيْتُمُوهَا وَأَقَمْتُمْ فِيهَا فَسَهْمُكُمْ فِيهَا وَأَيُّمَا قَرْيَةٍ عَصَتِ اللَّهَ وَرَسُولَهُ فَإِنَّ خُمُسَهَا لِلَّهِ وَلِلرَّسُولِ ثُمَّ هِيَ لَكُمْ " .
