Salman al-Farisi reported: The Messenger of Allah, peace and blessings be upon him, was asked about eating ghee, cheese, and wild donkeys. The Prophet said, “The lawful is what Allah has made lawful in His Book and the unlawful is what Allah has made unlawful in His book. Whatever He has been silent over has been pardoned.”

عَنْ سَلْمَانَ الْفَارِسِيِّ قَالَ سُئِلَ رَسُولُ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ عَنِ السَّمْنِ وَالْجُبْنِ وَالْفِرَاءِ فَقَالَ الْحَلَالُ مَا أَحَلَّ اللَّهُ فِي كِتَابِهِ وَالْحَرَامُ مَا حَرَّمَ اللَّهُ فِي كِتَابِهِ وَمَا سَكَتَ عَنْهُ فَهُوَ مِمَّا عَفَا عَنْهُ
