Taqwa (God-Consciousness)

On the authority of Abu Dharr Jundub ibn Junadah, and Abu Abdur-Rahman Muadh bin Jabal (may Allah be pleased with him), 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.
