Verse 23 of Surah Jinn says:
“For those who disobey God and his Messenger is Hell and they shall dwell in it forever.”
Verse 115 of Surah Nisaa says:
“Whoever opposes the Messenger after having received the guidance, following the path of the non-believers, We will make him what he has made himself and will cast him into Hell. What an evil destination it is.”
The word “Yushaaq” has been derived from “Shiqaaq” and means opposing some one with animosity and the sentence “after having received guidance” tells us that this spring forth from defiance and this is done to create rifts in the ranks of Muslims. Such people are the manifest examples for those who will go to Hell.
