What are the reasons that necessitate and those that do not necessitate interrupting recitation or remembrance (dhikr)? What is the ruling on resuming remembrance or recitation when it is interrupted by speech that is of the same kind as the remembrance or not of the same kind, and when returning a greeting of peace (salam) or enjoining good and forbidding evil? What is the ruling on the remembrance (adhkar) of sleep when it is interrupted by speech? Is it obligatory for them to be the last words one utters? What is the ruling on reciting Surat Al-Mulk after Isha and then again before sleep?

The reasons for interrupting recitation and remembrance (dhikr) can be summarized as: a need, an unforeseen circumstance, or the emergence of something whose time will pass or become constrained. Imam al-Nawawi summarized these situations, mentioning among them: returning a salam (greeting), saying "Yarhamukallah" to someone who sneezes, responding to the muezzin (call to prayer), removing an evil, guiding someone seeking guidance, overcoming drowsiness, and answering one's mother's call. It is disliked to interrupt recitation to speak to someone, except for matters directly related to the Quran itself, such as explaining a verse.
