The Prophet ﷺ said "Certainly a time will come when people will not bother to know from where they earned the money, by lawful means or unlawful means." (See Hadith no. 2050)
عَنِ النَّبِيِّ ﷺ قَالَ لَيَأْتِيَنَّ عَلَى النَّاسِ زَمَانٌ لاَ يُبَالِي الْمَرْءُ بِمَا أَخَذَ الْمَالَ أَمِنْ حَلاَلٍ أَمْ مِنْ حَرَامٍ
