Hadith 3:20
Ibn ‘Umar reported God’s messenger as saying, “Prayer without purification is not accepted, neither is sadaqa from the profits of un faithful dealing.” Muslim transmitted it.
وَعَنِ ابْنِ عُمَرَ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «لَا تُقْبَلُ صَلَاةُ بِغَيْرِ طُهُورٍ وَلَا صَدَقَةٌ مِنْ غُلُولٍ» . رَوَاهُ مُسلم
