3. Ali ibn Ibrahim has narrated from his father from al-Nawfali from al-Sakuni from Abu ‘Abdillah (a.s.) who has said the following: “The Messenger of Allah has said, ‘Beware of the prayer of an oppressed; it climbs over the cloud and Allah, the Most Majestic, the Most Holy, looks at it and says, “Raise it up so it is accepted,” and beware of the prayer of a father; it is sharper than a sword.’”
