I heard Messenger of Allah ﷺ saying, 'Both legal and illegal things are evident but in between them there are doubtful (suspicious) things and most of the people have no knowledge about them. So whoever saves himself from these suspicious things saves his religion and his honor. And whoever indulges in these suspicious things is like a shepherd who grazes (his animals) near the Hima (private pasture) of someone else and at any moment he is liable to get in it. (O people!) Beware! Every king has a Hima and the Hima of Allah on the earth is His illegal (forbidden) things. Beware! There is a piece of flesh in the body if it becomes good (reformed) the whole body becomes good but if it gets spoilt the whole body gets spoilt and that is the heart. (Using translation from Bukhārī 52)   

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ الْحَلَالُ بَيِّنٌ وَالْحَرَامُ بَيِّنٌ وَبَيْنَهُمَا مُشْتَبِهَاتٌ لَا يَعْلَمُهَا كَثِيرٌ مِنَ النَّاسِ فَمَنِ اتَّقَى الشُّبُهَاتِ اسْتَبْرَأَ لِعِرْضِهِ وَدِينِهِ وَمَنْ وَقَعَ فِي الشُّبُهَاتِ وَقَعَ فِي الْحَرَامِ كَالرَّاعِي يَرْعَى حَوْلَ الْحِمَى يُوشِكُ أَنْ يُوَاقِعَهُ ثُمَّ إنَّ لِكُلِّ مَلِكٍ حِمًى أَلَا وَإِنَّ حِمَى اللهِ مَحَارِمُهُ أَلَا إِنَّ فِي الْجَسَدِ مُضْغَةً إِذَا صَلُحَتْ صَلُحَ الْجَسَدُ كُلُّهُ وَإنْ فَسَدَتْ فَسَدَ الْجَسَدُ كُلُّهُ أَلَا وَهِيَ الْقَلْبُ  

[Machine] The Messenger of Allah ﷺ said: "The lawful is clear, and the unlawful is clear, and between them are doubtful matters. Whoever avoids doubtful matters, he keeps his religion and honor intact. But whoever falls into doubtful matters, he may fall into what is unlawful, just as a shepherd who grazes his flock around forbidden land may soon enter it."  

قَالَ رَسُولُ اللهِ ﷺ الْحَلَالُ بَيِّنٌ وَالْحَرَامُ بَيِّنٌ وَبَيْنَ ذَلِكَ أُمُورٌ مُشْتَبِهَةٌ فَمَنْ تَرَكَ مَا اشْتَبَهَ عَلَيْهِ كَانَ لِمَا اسْتَبَانَ لَهُ أَتْرَكَ وَمَنِ اجْتَرَأَ عَلَى مَا يَشُكُّ فِيهِ أَوْشَكَ أَنْ يُوَاقِعَ مَا اسْتَبَانَ لَهُ وَالْمَعَاصِي حِمَى اللهِ وَمَنْ يَرْتَعْ حَوْلَ الْحِمَى يُوشِكْ أَنْ يُوَاقِعَهُ  

[Machine] That the Messenger of Allah (Peace be upon him) said, "A time will come upon people when they would not care whether they earned money through lawful or unlawful means."  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ لَيَأْتِيَنَّ عَلَى النَّاسِ زَمَانٌ لَا يُبَالِي الْمَرْءُ بِمَا أَخَذَ الْمَالَ بِحَلَالٍ أَمْ بِحَرَامٍ
