"The Messenger of Allah said: 'There will come a time when a man will not care where his wealth comes from, whether (the source is) Halal or Haram." (Using translation from Nasāʾī 4454)
قَالَ رَسُولُ اللهِ ﷺ «يَأْتِي عَلَى النَّاسِ زَمَانٌ مَا يُبَالِي الرَّجُلُ مِنْ أَيْنَ أَصَابَ الْمَالَ مِنْ حِلٍّ أَوْ حَرَامٍ»
