Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) narrates this saying of the Prophet (peace and blessings be upon him): "Between the two leaves of a door of Paradise is a distance of forty years' travel."
Ahmad and Abu Ya'la recorded it; its narrators have been declared trustworthy despite weakness in them.
