Answered by Shaykh Faraz Rabbani
Would Asr prayer count if a person starts it somewhere before dusk & finishes it only after the sunset?
Answer:
In the Name of Allah, Most Merciful and Compassionate
Walaikum assalam wa rahmatullah,
It would be a current performance.
However, one would be sinful for two matters:
a) delaying performance of Asr until the prohibited time (which is sinful and prohibitively disliked even when one is busy) [Ibn Abidin, Radd al-Muhtar]
b) not completing the prayer within the time, which is obligatory. [Shurunbulali, Imdad al-Fattah]
And Allah alone gives success.
Wassalam,
Faraz Rabbani
