Allah ﷻ ˹audits˺ his creation during the night of the middle of ˹month of ˺ Shaʿbān then forgives those seeking forgiveness and pardons those who are repenting, leaves the people of hate in their hatefulness, and forgives ˹others˺ except for the one who associates partners with Him or one filled with malice."
