Have Wondered Why Some People Cry, Scream and Faint When They Attend Music Shows of Their Idolised Musician?!

In The Name of Allaah, The Most Merciful, The Bestower of Mercy.

Imaam Ibnul Qayyim [rahimahullaah] said: Hearts that are emptied of Love for Allaah -hearts that are turned away from Him and seeking remedy from others besides Him- are afflicted with an infatuation with images; for when the heart is filled with Love of Allaah and a strong love for meeting Him [i.e. in the hereafter], this infatuation with images is repelled from it.  And for this reason, Allaah [The Most High] stated about Yusuf [alayhis-salaam]:

[كَذَٰلِكَ لِنَصْرِفَ عَنْهُ السُّوءَ وَالْفَحْشَاءَ ۚ إِنَّهُ مِنْ عِبَادِنَا الْمُخْلَصِينَ -Thus it was, that We might turn away from him evil and illegal sexual intercourse. Surely, he was one of Our chosen, guided slaves]. This shows that sincerity to [Allaah] is a means to repelling [evil]. And because of this, some of the Salaf said: ‘’Infatuation is an agitation in empty hearts.” Meaning: [Hearts] emptied of other than what they crave for.
