Explanation

The meaning in a few plain lines

The Prophet (ﷺ) enjoins three things: First: fear of Allah, by fulfilling the duties and avoiding the prohibitions, in every place, time, and condition, and in secret and public, and at good times and bad ones, and so on. Second: If you fall into a sin, do a good deed after it, like prayer, charity, an act of kindness, upholding kinship ties, repentance, etc., for that erases the sin. Third: Treat people with good morals, like smiling at them, showing them gentleness and leniency, doing good to them, and averting harm from them.
