1626. hadíth
وَ رَوَى اَلْحَسَنُ بْنُ مَحْبُوبٍ عَنْ عَبْدِ اَللَّهِ بْنِ سِنَانٍ قَالَ قَالَ أَبُو عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ: "كُلُّ شَيْءٍ يَكُونُ فِيهِ حَلاَلٌ وَ حَرَامٌ فَهُوَ لَكَ حَلاَلٌ أَبَداً حَتَّى تَعْرِفَ اَلْحَرَامَ مِنْهُ بِعَيْنِهِ فَتَدَعَهُ ".
It is narrated from Al-Hasan ibn Mahbub, from Abdullah ibn Sinan, who said: Abu Abdullah (a.s), said: "Everything that contains both lawful and unlawful elements is always lawful for you until you specifically identify the unlawful part, at which point you must avoid it."
