Allah SWT know best.
When an individual's heart is illuminated by the true light of Islam - no being besides Allah the Almighty can misguide him/her.
When an individual's heart is truly filled with the love of his creator and our beloved prophet Muhammad Mustafa (SAW) - no being besides Allah the Almighty can misguide him/her.
Islam is the only perfect way of life and if one leaves this religion - Allah had written for him/her to be misguided.
May Allah (SWT) inculcate in us the true ability to love and fear him.
May he guide us to follow the beautiful teachings our our beloved prophet Muhammad Mustafa (SAW).
May he keep us steadfast on our deen.
May he be pleased us when we depart from this world.
May he bless us with Jannatul-Firdaus.
Aameen.
