But among them was a man called Dhul-Yadain who said: Messenger of Allah, has the prayer been shortened or have you forgotten? The Messenger of Allah (ﷺ) looked to the right and left and said: What was Dhul-Yadain saying? They said: He is right. You (the Holy Prophet) offered but two rak`ahs. He offered two (more) rak`ahs and gave salutation, then said takbir and prostrated and lifted (his head) and then said takbir and prostrated, then said takbir and lifted (his head).
