In this case, one-fifth belongs to Allah and the tribute belongs to the Muslims."  

البيهقي:١٨٠٠٠ – أَخْبَرَنَا أَبُو نَصْرِ بْنُ قَتَادَةَ أنبأ أَبُو الْفَضْلِ بْنُ خَمِيرَوَيْهِ ثنا أَحْمَدُ بْنُ نَجْدَةَ ثنا الْحَسَنُ بْنُ الرَّبِيعِ ثنا عَبْدُ اللهِ بْنُ الْمُبَارَكِ عَنِ الْأَوْزَاعِيِّ حَدَّثَنِي أُسَيْدُ بْنُ عَبْدِ الرَّحْمَنِ عَنْ خَالِدِ بْنِ الدُّرَيْكِ قَالَ سَأَلْتُ ابْنَ مُحَيْرِيزٍ عَنْ بَيْعِ الطَّعَامِ وَالْعَلَفِ بِأَرْضِ الرُّومِ فَقَالَ سَمِعْتُ فَضَالَةَ بْنَ عُبَيْدٍ ؓ يَقُولُ إِنَّ رِجَالًا يُرِيدُونَ أَنْ يُزِيلُونِي
