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

‌عَنْ ‌أَبِي ‌ذَرٍّ، ‌جُنْدُبِ ‌بْنِ ‌جُنَادَةَ، ‌وَأَبِي ‌عَبْدِ ‌الرَّحْمَنِ، ‌مُعَاذِ بْنِ جَبَلٍ رَضِيَ اللَّهُ عَنْهُمَا عَنْ رَسُولِ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ قَالَ:
«اتَّقِ اللَّهَ حَيْثُمَا كُنْت، وَأَتْبِعْ السَّيِّئَةَ الْحَسَنَةَ تَمْحُهَا، وَخَالِقْ النَّاسَ بِخُلُقٍ حَسَنٍ».
[قال الترمذي: حديث حسن] - [رواه الترمذي] - [الأربعون النووية: 18]

Abu Dharr, Jundub ibn Junādah, and Abu ‘Abdur-Rahmān, Mu‘ādh ibn Jabal (may Allah be pleased with both of them) reported that the Messenger of Allah (ﷺ) 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."
[قال الترمذي: حديث حسن] - [Narrated by At-Termedhy] - [الأربعون النووية - 18]

Explanation

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.
