Hadith: Fear Allah wherever you are, follow a bad deed with a good deed and it will erase it, and treat people with good morals

عن أبي ذر و معاذ بن جبل رضي الله عنهما عن النبي صلى الله عليه وسلم قال: «اتق الله حيثما كنت، وأَتْبِع السيئةَ الحسنةَ تمحها، وخالقِ الناسَ بخلقٍ حسنٍ».
[حسن] - [حديث أبي ذر: رواه الترمذي وأحمد والدارمي. حديث معاذ -رضي الله عنه-: رواه الترمذي وأحمد]

Abu Dharr and Mu‘ādh ibn Jabal (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: "Fear Allah wherever you are, follow a bad deed with a good deed and it will erase it, and treat people with good morals."
[Good hadith] - [Narrated by At-Termedhy - Narrated by Ahmad - Ad-Daarimi]

Explanation

Fear Allah by obeying His commands and avoiding His prohibitions wherever you may be, follow a bad deed with a good one to expiate it and wipe out its bad effects from the heart and its penalty from your record of deeds, and treat people as you would like them to treat you.
