Ref. No. 41/0000
In the name of Allah the most Gracious the most Merciful
The answer to your question is as follows:
Naming ‘Gul’ as mentioned in the question is not permissible. People should avoid using such guls. Nevertheless if a person has used it, he/she must not throw the gul packets containing mention of Allah’s name on the ground or in dirty places. So that it will not lead to disrespect the name of Allah.
And Allah knows best
