Sayyiduna Umar bin Khattab (may Allah be pleased with him) narrates that the Prophet Muhammad (peace and blessings be upon him) said: "Whoever sleeps before performing his regular practice (wird) or something from it remains, then if he recites it between the Fajr prayer and the Zuhr prayer the next day, it will be recorded for him in his book of deeds just as if he had recited it at night."
