Question:
Is it permissible to pray behind the people or imam who follow ibadi madhab, particularly in Oman.It is not among the four madhabs followed by the Ahlus sunnah Jamaah.
Answer:
Yes, it is permissible since Abd Allah ibn Umar (RA) was stricter in following Sunna and Jamaah than a million of you and me and he used to pray even behind the Khawarij and he would say, “If one says Hayya `ala al-Salat” I respond.
