The Hanafis confess that according to their bizarre and un-Islamic “jurisprudence”, Tarteeb (performing the actions in sequence) is merely Sunnah and not Fard (obligatory). This means, a person who does Wudu against the proper sequence, for example, washing his feet first rather than last, or wiping the head before washing the face, etc., such a person's actions will complete his Wudu:
وَالتَّرْتِيبُ فِي الوُضُوءِ سَنَةٌ عِنْدَنَا، وَعِنْدَ الشافعي - رَحِمَهُ الله - فَرْضٌ
Translation: And Tarteeb (Sequence) in Wudoo is only Sunnah according to us, but according to Imam Shafi'ie (rahimahullah) it is Fard (obligatory).
