He Vowed to Pray Ten Rak'ahs, Should He Pray Them All in One Day?

Question :

I vowed to Allah, Most Glorified, Most High that I would pray ten Rak'ahs if the pain in my leg decreased.

Now I do not know if I should pray the ten Rak'ahs, praying them two each day until I have completed them, which would be after five days, or must I pray the ten at one time, I mean, in one day? Benefit me (with advice) and may Allah benefit you (with a reward).

Answer:

If the aforementioned condition-which was a decrease in the pain was fulfilled, then you must execute your vow immediately and pray ten Rak'ahs at a time when prayer is not forbidden, making Taslim at the end of every two Rak'ahs, in accordance with the saying of the Prophet ﷺ:
"Whoever vowed to obey Allah, he should obey Him and whoever vowed to disobey Allah, he should not disobey Him."
