Chapter 8 | What Allah (azwj) has Forbidden a Believer to do Against a Fellow Believer
183 - وعن أبي عبد الله عليه السلام أنه قال: من أدخل السرور على مؤمن فقد أدخله على رسول الله صلى الله عليه وآله وسلم، ومن أدخل على رسول الله صلى الله عليه وآله وسلم فقد وصل ذلك إلى الله عز وجل، وكذلك من أدخل عليه كربا.
183. It has been reported that Abu 'Abd Allah said: One who brings happiness to a believer has in fact brought it to the Messenger of Allah ; and one who brings happiness to the Messenger of Allah has had the happiness reached Allah [M.G]; and the same is for one who causes him distress.
