i really like what abu sabaya said regarding a murtad:

“As for the reasons behind his leaving Islam, this is too complicated and private to discuss here, but let me say this: it was the inevitable outcome of practicing a dry Islam that consists of reading mostly news all day, following only controversial topics and debates, and having little time for worship and purification of his heart. Go back and look at his posts, and you’ll see that I’m right.

When we look at people who we assume to be ‘good brothers,’ we often misinterpret revolutionary spirit to be sincere enthusiasm for the religion, while it’s possible that for that person, Islam is just the flavor of the month. The biggest sign of this is when you notice the person rarely focusing on heart-softeners in his reading or speech, never performing optional acts of worship, and not trying to grasp Islam as a whole. Rather, they only pick up on the controversies and entertaining issues because they entered Islam in the first place mainly out of a desire to be part of something against the grain, something that stands out, as opposed as to a sincere desire to submit to Allah. Once the flavor of the gum fades, you want a new piece. This was 99% of the reason that he couldn’t stay on board in the end, and I fear for some who I see displaying the same symptoms.

Save yourself before it is too late”
