"Fear Allah wherever you are"
On the authority of Abu Dharr Jundub ibn Junadah, and Abu Abdur-Rahman Muadh bin Jabal (may Allah be pleased with them), that the Messenger of Allah (peace and blessings of Allah be upon him) said:
"Have Taqwa (fear) of Allah wherever you may be, and follow up a bad deed with a good deed which will wipe it out, and behave well towards the people. It was related by at-Tirmidhi, who said it was a Hasan (good) Hadeeth, and in some copies it is stated to be a Hasan Saheeh hadeeth."
It was narrated by Ahmad and at-Tirmidhi and Abu Dawood on the authority of Abu Dharr. It was narrated by Ahmad and at-Tirmidhi on the authority of Mu'adh ibn Jabal. It is classed as Hasan by al-Albani.
