A long interval between the two prayers invalidates combining them

Question:
May Allah reward you with good and do you good. After this, there is a message from Umm 'Ata asking and saying: Does the one who wants to combine the two prayers for an excuse have to not separate them with an interval, such as speech, sleep, or something else? Yes. Does the one who wants to combine the two prayers for an excuse have to not separate them with an interval, such as speech, sleep, or something else?

Answer:
Yes. The one who wants to combine the two prayers, and combining is permissible for him, whether due to illness, travel, or rain that wets the clothes or mud, must observe the condition of continuity between the two prayers. This means he must not separate them except with a brief interval for ablution or a light need. As for sleep, or a long interval, this invalidates the combining. As for speech, it does not invalidate the combining if he speaks after the first prayer, especially if the speech is for a need, for this does not invalidate the combining. Yes.
