As-sallamu alaykum; insha-ALLAH i would like to know when making sunnah prayers do you salam out after two then offer the other two like in the sunnahs before salaatul thuhr or do you offer the four ra'kas like performing salaatul thuhr or asr
It is preferable to pray them two by two, saying the salam after every two rakahs. For more information please see question # 1048.
