وَعَنِ ابْنِ عُمَرَ
قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «لَا تُقْبَلُ صَلَاةُ بِغَيْرِ طُهُورٍ وَلَا صَدَقَةٌ مِنْ غُلُولٍ»
Ibn Umar reported God’s messenger as saying, “Prayer without purification is not accepted, neither is sadaqa from the profits of un faithful dealing.”
