Salam, I would like to change my childrens name as one of my child is called Falak ( it means sky and also a snake in hell) who can I pick a name out of the holy quran. is there an imam out there who can help me. shukran

Alaikumassalam,

There is no need to change the name Falak, because the two meanings you mentioned are for two completely different words. One of them is Falak, written as فلك in Arabic, which is a good name whose meaning you can see here: Falak

The other word is Falaq, written as فلق, which means "hellfire" and has other negative meanings.

These two words come from two different roots and have no relation with each other, for this reason there is no need to change the name.
