Answered by Mawlana Ilyas Patel
I recently discovered that glue could be made from animal derivatives (including pork gelatin etc.). Glue is found in many different things. Does this mean I have to investigate objects that use glue to understand whether it is impure (najis)?
In the Name of Allah, the Most Merciful and Compassionate
Glue made from animal derivatives is permissible except for pork-derived. However, if one comes to know that a particular glue is made from it, then it will be impermissible to use. Glue is made from a wide range of raw materials, so one can assume it is from other than pork derived. One does not have to investigate a specific product if it is made from a pork derivative.
One can apply this principle, and also to many things in life.
“The normal basis for all things is that they are permissible until there is evidence of impermissibility.” [Ibn Nujaym, Al-Ashbah Wa al-Nadhair]
If the glue does not show impermissibility, you have no obligation to consider whether it has been derived from animal or non-animal-based gelatin.
