عَن بُرَيْدَةَ عَنِ
النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «مَنِ اسْتَعْمَلْنَاهُ عَلَى عَمَلٍ فَرَزَقْنَاهُ رِزْقًا فَمَا أَخَذَ بَعْدَ ذَلِكَ فَهُوَ غُلُولٌ»
The Prophet (sallallahu alayhi wa sallam) said:, “When we appoint someone to an administrative post and provide him with an allowance, anything he takes beyond that is unfaithful dealing.”
