My repected Mufti Saheb, I would just like to know that when I go in Jamaat and I�am a Musaafir if I should perform my Sunnah Salaah or if I should complete my Qadha Salaah instead.
Do not leave out your Sunnat-e-Muakkidah. However if you do you will not be sinful. Rather read your Qadha Salaat in place of your Sunnat-e-Ghair-Muakkidah and Nafl Salaats.
