"I heard the Messenger of Allah say: "That which is lawful is plain and that which is unlawful is plain, and between them are matters which are not as clear. I will strike a parable for you about that: indeed Allah, the Mighty and Sublime, has established a sanctuary, and the sanctuary of Allah is that which He has forbidden. Whoever approaches the sanctuary is bound to transgress upon it, Or he said: 'Whoever grazes around the sanctuary will soon transgress upon it, and whoever indulges in matters that are not clear, he will soon transgress beyond the limits,""  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ فَوَاللَّهِ لاَ أَسْمَعُ بَعْدَهُ أَحَدًا يَقُولُ سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ إِنَّ الْحَلاَلَ بَيِّنٌ وَإِنَّ الْحَرَامَ بَيِّنٌ وَإِنَّ بَيْنَ ذَلِكَ أُمُورًا مُشْتَبِهَاتٍ وَرُبَّمَا قَالَ وَإِنَّ بَيْنَ ذَلِكَ أُمُورًا مُشْتَبِهَةً قَالَ وَسَأَضْرِبُ لَكُمْ فِي ذَلِكَ مَثَلاً إِنَّ اللَّهَ ﷻ حَمَى حِمًى وَإِنَّ حِمَى اللَّهِ ﷻ مَا حَرَّمَ وَإِنَّهُ مَنْ يَرْتَعْ حَوْلَ الْحِمَى يُوشِكْ أَنْ يُخَالِطَ الْحِمَى وَرُبَّمَا قَالَ إِنَّهُ مَنْ يَرْعَى حَوْلَ الْحِمَى يُوشِكْ أَنْ يَرْتَعَ فِيهِ وَإِنَّ مَنْ يُخَالِطِ الرِّيبَةَ يُوشِكْ أَنْ يَجْسُرَ  

"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."  

قَالَ رَسُولُ اللَّهِ ﷺ يَأْتِي عَلَى النَّاسِ زَمَانٌ مَا يُبَالِي الرَّجُلُ مِنْ أَيْنَ أَصَابَ الْمَالَ مِنْ حَلاَلٍ أَوْ حَرَامٍ  

"The Messenger of Allah said: "There will come a time when there will be no one left who does not consume Riba, and whoever does not consume it will nevertheless be affected by residue." (Sahih )  

قَالَ رَسُولُ اللَّهِ ﷺ يَأْتِي عَلَى النَّاسِ زَمَانٌ يَأْكُلُونَ الرِّبَا فَمَنْ لَمْ يَأْكُلْهُ أَصَابَهُ مِنْ غُبَارِهِ
