Kindly refer to the following link(s):
Is it Sunnah 2 Refute Scholars Daees or Watch Channels that expose disbelievers defaming Islam
Is exposing people on Social Media the same as Protesting? Speaking ill about Muslim Rulers
Take the good & leave the evil: Should we cooperate with people of innovation & Shirk
Talking on YouTube about public figures got exposed backbiting or warning others?
A popular Sheikh refuted Sheikh Assim al Hakeem?
Can we warn people about a Mawlana who says it's ok to wish Christmas, New year etc?
Tarnishing people's reputation by asking about them on live television, social media backbite
Youth must avoid labeling others, stop refuting on YouTube
