Distance yourself from matters of doubt since what is permissible or prohibited has already been made clear

I heard the Messenger of Allah ﷺ say –and al-Nu‘man gestured with his two fingers toward his ears–: “Indeed, what is lawful is clear, and what is unlawful is clear, and between them are doubtful matters that many people do not know. Whoever avoids the doubtful matters has safeguarded his religion and his honor; and whoever falls into the doubtful matters falls into the unlawful. ˹This is˺ like a shepherd who grazes around a protected sanctuary, and is about to graze within it. Indeed, every king has a sanctuary; indeed, the sanctuary of Allah is His prohibitions. Indeed, in the body there is a morsel of flesh: if it is sound, the whole body is sound; and if it is corrupt, the whole body is corrupt. Indeed, it is the heart.”

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ، وَأَهْوَى النُّعْمَانُ بِإِصْبَعَيْهِ إِلَى أُذُنَيْهِ: «إِنَّ الْحَلَالَ بَيِّنٌ، وَإِنَّ الْحَرَامَ بَيِّنٌ، وَبَيْنَهُمَا مُشْتَبِهَاتٌ لَا 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. أَلَا وَإِنَّ لِكُلِّ مَلِكٍ حِمًى، أَلَا وَإِنَّ حِمَى اللَّهِ مَحَارِمُهُ. أَلَا وَإِنَّ فِي الْجَسَدِ مُضْغَةً، إِذَا صَلَحَتْ صَلَحَ الْجَسَدُ كُلُّهُ، وَإِذَا فَسَدَتْ فَسَدَ الْجَسَدُ كُلُّهُ، أَلَا وَهِيَ الْقَلْبُ».
