Taking that which is lawful and leaving that which is unclear

Nu'man b. Bashir (Allah be pleased with him) reported:
I heard Messenger of Allah ﷺ as having said this (and Nu'man) pointed towards his ears with his fingers): What is lawful is evident and what is unlawful is evident, and in between them are the things doubtful which many people do not know. So he who guards against doubtful things keeps his religion and honour blameless, and he who indulges in doubtful things indulges in fact in unlawful things, just as a shepherd who pastures his animals round a preserve will soon pasture them in it. Beware, every king has a preserve, and the things God his declared unlawful are His preserves. Beware, in the body there is a piece of flesh; if it is sound, the whole body is sound and if it is corrupt the whole body is corrupt, and hearken it is the heart.

حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ نُمَيْرٍ الْهَمْدَانِيُّ، حَدَّثَنَا أَبِي، حَدَّثَنَا زَكَرِيَّاءُ، عَنِ الشَّعْبِيِّ، عَنِ النُّعْمَانِ بْنِ بَشِيرٍ، قَالَ سَمِعْتُهُ يَقُولُ سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ وَأَهْوَى النُّعْمَانُ بِإِصْبَعَيْهِ إِلَى أُذُنَيْهِ
" إِنَّ الْحَلاَلَ بَيِّنٌ وَإِنَّ الْحَرَامَ بَيِّنٌ وَبَيْنَهُمَا مُشْتَبِهَاتٌ لاَ يَعْلَمُهُنَّ كَثِيرٌ مِنَ النَّاسِ فَمَنِ اتَّقَى الشُّبُهَاتِ اسْتَبْرَأَ لِدِينِهِ وَعِرْضِهِ وَمَنْ وَقَعَ فِي الشُّبُهَاتِ وَقَعَ فِي الْحَرَامِ كَالرَّاعِي يَرْعَى حَوْلَ الْحِمَى يُوشِكُ أَنْ يَرْتَعَ فِيهِ أَلاَ وَإِنَّ لِكُلِّ مَلِكٍ حِمًى أَلاَ وَإِنَّ حِمَى اللَّهِ مَحَارِمُهُ أَلاَ وَإِنَّ فِي الْجَسَدِ مُضْغَةً إِذَا صَلَحَتْ صَلَحَ الْجَسَدُ كُلُّهُ وَإِذَا فَسَدَتْ فَسَدَ الْجَسَدُ كُلُّهُ أَلاَ وَهِيَ الْقَلْبُ " .

This hadith has been narrated on the authority of Zakariya with the same chain of transmitters.

وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا وَكِيعٌ، ح وَحَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، أَخْبَرَنَا عِيسَى بْنُ يُونُسَ، قَالاَ حَدَّثَنَا زَكَرِيَّاءُ، بِهَذَا الإِسْنَادِ مِثْلَهُ .

AI-Nu'man b. Bashir reported it from Allah's Apostle ﷺ. The hadith narrated by Zakariya is, however, more complete and lengthy than the other ones.

وَحَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، أَخْبَرَنَا جَرِيرٌ، عَنْ مُطَرِّفٍ، وَأَبِي، فَرْوَةَ الْهَمْدَانِيِّ ح وَحَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا يَعْقُوبُ، - يَعْنِي ابْنَ عَبْدِ الرَّحْمَنِ الْقَارِيَّ - عَنِ ابْنِ عَجْلاَنَ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ سَعِيدٍ، كُلُّهُمْ عَنِ الشَّعْبِيِّ، عَنِ النُّعْمَانِ بْنِ بَشِيرٍ، عَنِ النَّبِيِّ ﷺ بِهَذَا الْحَدِيثِ غَيْرَ أَنَّ حَدِيثَ زَكَرِيَّاءَ أَتَمُّ مِنْ حَدِيثِهِمْ وَأَكْثَرُ .
