Assalaamu aleykum, is it permissible for a traveler to fast maybe if d travel falls on Sunday or Thursday if he is capable of doing so?
Wa alaikum salam.
As for Thursday, there is no harm if a traveler fasts it, as long as it’s not difficult for him.
As for fasting voluntary fast on Sunday alone, Scholars differ. Some see it as haram, while others say it is Makroo’. It is better to leave it of doesn’t fall on one of the days of special Sunnah fasts
