Assalamualaikum warrahmatullahi wabarakatuh
I have phone that have WhatsApp and in the WhatsApp i have class group chat on it , i have need on that group chat and i found out that the group chat have evil on it.
Is it permisible to use my phone and WhatsApp as long as i not open the group chat?

All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.

There is no harm on you in using your mobile phone, but do not enter this group except when you need to do so.

If you find any violations of the Sharee’ah, then you should advise them gently and wisely.

Allah Knows best.
