The World Federation One Stop Fiqh

Ruling 1364

With regard to someone who has only one qaḍāʾ prayer from the past, it is better that if the prime time of that day’s prayer will not expire, he should first perform the qaḍāʾ prayer and then start performing his daily prayer. Similarly, if he does not have any qaḍāʾ prayers from the past but on that day one or more of his prayers became qaḍāʾ, then, if the prime time of his prayer will not expire, it is better that he perform that day’s qaḍāʾ prayers before he performs the adāʾ prayers.
