Musaafir leaving out the Sunnat Salaah
Q: If a person is a musaafir, eg on jamaat
1) If moving from masjid to masjid in one locality, and will stay in that locality for more than 15 days, does he become muqeem?
2) If he continuously leaves out the sunnats whilst a musafir, eg whilst on jamaat, I know this is not correct, but does he become a sinner?
