Does not praying at the beginning of the appointed time mean that one’s du’aa’ will not be answered?
Question

                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 Allah.Shaykh Abd-Allaah ibn Qaood answered this question for us
    as follows:
We do not know of any evidence to that effect. Allaah may answer the
    duaa of one who calls on Him in desperation even if he is a kaafir. And Allaah
    knows best.
