"The Messenger of Allah ﷺ was asked about fat, cheese, and furs, so he said: 'The lawful is what Allah made lawful in His Book, the unlawful is what Allah made unlawful in his Book, and what He was silent about; then it is among that for which He has pardoned.'"
سُئِلَ رَسُولُ اللَّهِ ﷺ عَنِ السَّمْنِ وَالْجُبْنِ وَالْفِرَاءِ فَقَالَ الْحَلاَلُ مَا أَحَلَّ اللَّهُ فِي كِتَابِهِ وَالْحَرَامُ مَا حَرَّمَ اللَّهُ فِي كِتَابِهِ وَمَا سَكَتَ عَنْهُ فَهُوَ مِمَّا عَفَا عَنْهُ
