Ṣaḥīḥ al-Bukhārī Ḥadīth [2083] – Negligence with regards to earning lawfully or unlawfully

حَدَّثَنَا آدَمُ، حَدَّثَنَا ابْنُ أَبِي ذِئْبٍ، حَدَّثَنَا سَعِيدٌ المَقْبُرِيُّ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ، قَالَ: لَيَأْتِيَنَّ عَلَى النَّاسِ زَمَانٌ، لاَ يُبَالِي المَرْءُ بِمَا أَخَذَ المَالَ، أَمِنْ حَلاَلٍ أَمْ مِنْ حَرَامٍ

Book [34]: Sales and trade
Chapter [23]: The statement of Allāh – the exalted: ‘O you who believe! Eat not ribā (usury), doubled and multiplied…’ [Sūrah Āl-‘Imrān 3: 130]

Ḥadīth [2083]: It is narrated on the authority of Abī Hurayrah (may Allāh be pleased with him) that the Prophet (peace and blessings of Allāh be upon him) 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.”
