- " ما من صلاة مفروضة إلا وبين يديها ركعتان ".
It is narrated from Sayyiduna Abdullah bin Zubair (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "There is no obligatory prayer except that before it there are (at least) two units (rak‘ahs) of voluntary prayer."
