As regards the 10-day rule for qasr salaat, what is considered to be a day? e.g. if one arrives at a place at 12.30pm on 1st june and leaves at 1.00am on 11th June, has he completed 10 days?
From 12:30pm on 1st June to 12:30pm on 2nd June, would be counted as one day. As per the question, he has not completed 10 days and so, he would be
required to recite qasr prayers while on travel.
