Planning to Repent Later?

Ibn Al-Qayyim, may Allāh have mercy on him, said:

Most of what makes a Muslim fall into sin is [his] “relying on [a later] repentance.” If he knew that [something] could come between him and it, his fear would be greatly agitated.

Ṭarīq Al-Hijratain, p. 562, as quoted by Shk. Fawāz Al-Madkhalī. 5 Mar 2020.
