In Al Musnad it is narrated that Anas R.A said that a jewish man asked the Prophet P.B.U.H to be his guest and he offered him some barley bread and melted grease.
In the Sahih it is is also narrated that Abdullah bin Mughaffal said ‘on the day if Khaibar, a bag full of grease was lowered and I took possession of it and said by Allah I will not give anyone any of it!
When I turned around I found that the Messenger of Allah P.B.U.H was laughing and did not comment.
The best type of grease is that taken from a grown animal. Grease is hot and wet but less wet than clarified butter. This is why when both grease and clarified butter are melted, grease hardens faster.
Grease helps against throat roughness, it represses and causes rotting. To neutralise the harmful effects of grease, one should use ,lemon , salt and ginger. Also, goat grease constipates more than any other type of grease, while billy goat grease is more decomposing and helps against stomach ulcer. Goat grease helps against stomach ulcer and is used as an injection to relieve excoriation (the rubbing away of skin from injury or disease), and tenesmus (spasms of the bladder or anus).
