وَعَنْ صُهَيْبٍ
قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَا آمَنَ بِالْقُرْآنِ مَنِ اسْتَحَلَّ مَحَارِمَهُ»
Suhayb reported God’s messenger as saying, “He who treats what the Qur’an prohibits as permissible does not believe in it.” Tirmidhi transmitted it, but said this is a tradition whose isnad is not strong.
