Is it obligatory to remove the fats and oils that stick to the hand before beginning the ablution?

The questioner : If you would allow me, while eating, there might be, for example, fats in the food and something else, so there would be a fatty substance on the skin. So it is the same as the previous question: Is it obligatory to remove this substance from the hands after eating, or is it possible for a person to perform the ablution?

The Shaykh : He performs the ablution, because this is removed by water, especially if there is soap or sidr. As for things that act as a barrier, these must be removed, such as paint, for example.

The questioner : Okay, and this cooking oil, the oil that is on the food, is it not considered a barrier, O our Shaykh? The oil and ghee and the like, do they not form a barrier layer?

The Shaykh: No.
