We follow in every matter of religion, the Prophet Muhammad (SAWA) through the most authentic source who are his Progeny (Ahlul Bayt) (AS). Our Wudhu, Ghusl, Salaah, Hajj, fasting, etc is exactly according to the Prophet’s real and most authentic teachings.
Those who have different way or ways should be asked why they left the most authentic Sunnah of the Prophet and followed others?
Wassalam.
