‘Uqba b. ‘Amir reported God’s Messenger as saying, “<i>Sahib maks</i>, meaning one who tithes people, will not enter paradise.” Ahmad, Abu Dawud and Darimi transmitted it.

وَعَنْ عُقْبَةَ بْنِ عَامِرٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «لَا يَدْخُلُ الْجَنَّةَ صَاحِبُ مَكْسٍ» : يَعْنِي الَّذِي يَعْشُرُ النَّاسَ. رَوَاهُ أَحْمد وَأَبُو دَاوُد والدارمي
