Abu Musa al-Ash‘ari reported God’s Messenger as saying, “God most high looks down on the middle night of Sha'ban and forgives all His creatures, except a polytheist or one who is hostile.”
Ibn Majah transmitted it, and Ahmad transmitted it from ‘Abdallah b. ‘Amr b. al-‘As. His version has, “except two, one who is hostile and a murderer.”
