QAs-salamu `alaykum. I vowed to fast for 40 Fridays. But now I heard that we can’t fast Friday alone. So what I am doing now is fasting Friday and Saturday or Thursday and Friday. It’s a vowed fast. I vowed only for Friday. Can I fast Friday alone? Or should I combine two days together?

Wa `alaykum as-salamu wa rahmatullahi wa barakatuh.
We are discouraged from fasting on Fridays unless it is Ramadan or the days when fasting is prescribed. So, if you have made a vow to fast forty Fridays, you can fast other days to make up for the number. It is important to remember that Friday is our weekly Eid.
