Sunan at-Tirmithiy كتاب البيوع باب ما جاء فى ترك الشبهات

حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ أَنْبَأَنَا حَمَّادُ بْنُ زَيْدٍ عَنْ مُجَالِدٍ عَنِ الشَّعْبِىِّ عَنِ النُّعْمَانِ بْنِ بَشِيرٍ قَالَ سَمِعْتُ رَسُولَ اللَّهُ صلى الله عليه وسلم يَقُولُ الْحَلاَلُ بَيِّنٌ وَالْحَرَامُ بَيِّنٌ وَبَيْنَ ذَلِكَ أُمُورٌ مُشْتَبِهَاتٌ لاَ يَدْرِى كَثِيرٌ مِنَ النَّاسِ أَمِنَ الْحَلاَلِ هِىَ أَمْ مِنَ الْحَرَامِ فَمَنْ تَرَكَهَا اسْتِبْرَاءً لِدِينِهِ وَعِرْضِهِ فَقَدْ سَلِمَ وَمَنْ وَاقَعَ شَيْئًا مِنْهَا يُوشِكُ أَنْ يُوَاقِعَ الْحَرَامَ كَمَا أَنَّهُ مَنْ يَرْعَى حَوْلَ الْحِمَى يُوشِكُ أَنْ يُوَاقِعَهُ أَلاَ وَإِنَّ لِكُلِّ مَلِكٍ حِمًى أَلاَ وَإِنَّ حِمَى اللَّهِ مَحَارِمُهُ.
The Messenger of God, peace and blessings of God be upon him, said, "What is permissible is clear and what is forbidden is clear (as defined by God), and between them are ambiguous matters that many people fail to place among the permissible or the forbidden. Whoever refrains from them, seeking to keep their religion and virtue blameless, will be safe. Whoever falls into doubtful matters, may fall into that which is forbidden. They are like those who graze their animals around a preserve (1) and come close to trespassing on it. Every king has a preserve, and indeed, God's preserve is whatever He has forbidden." Footnotes: (1) A sanctuary: royally designated land prohibited for grazing by other than the king's livestock. Click on ḥadīth to read more
