Abdur Rahman bin Abdul Qari narrates that I heard Umar bin Khattab (may Allah be pleased with him) say, the Messenger of Allah (peace and blessings be upon him) said: "Whoever sleeps through his regular recitation or a part of it, then recites that portion between the Fajr and Dhuhr prayers (by reciting it and offering it as voluntary prayer), it will be written for him as if he had recited that portion during the night."
