Narrated Salman: "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'." Abu 'Eisa said: There is something on this topic from Al-Mughirah, and this Hadith is Gharib, we do not know of it being Marfu' except from this route. Sufyan and others reported it from Sulaiman At-Taimi, from Abu 'Uthman, from Salman as his own saying. It is as if the Mawquf narration is more correct. I asked Al-Bukhari about this Hadith and he said: 'I do not think it is preserved. Sufyan reported it from Sulaiman At-Taimi from Abu 'Uthman, from Salman in Mawquf form'. Al-Bukhari said: "Saif bin Harun is Muqarib (Average) in Hadith, and as for Saif bin Muhammad from 'Asim, his narrations are left".
The Prophet Muhammad (PBUH) was asked about certain items such as fat, cheese and furs and he responded by saying that whatever Allah has made lawful in His Book should be followed while anything He did not mention can be forgiven. This means that if something isn't explicitly forbidden by Allah then it can still be done but with caution as there may still be some harm associated with it or other reasons why it might not be recommended for a believer's lifestyle. It also teaches us that we must always refer back to the teachings of Allah for guidance on matters related to our faith instead of relying on our own judgement or opinions which could lead us astray from His path.
