Is there any evidence that one who delays prayer from its recommended time (but prays in its legal time) and who makes post-salah
du’ah does not have his/her du’ah accepted?

Praise be to Allaah.

Shaykh ‘Abd-Allaah ibn Qa’ood answered this question for us
as follows:

Praise be to Allaah.

We do not know of any evidence to that effect. Allaah may answer the
du’aa’ of one who calls on Him in desperation even if he is a kaafir. And Allaah
knows best.”
