It is very important for every Muslim to make sure that his choice of friends and the company he keeps is correct. It has been proven through experience that habits and behaviour of friends and associates slowly manifest in an individual. Without realizing, a person begins to adopt the style and behaviour of his friends. We are all witness to this fact. Sadly, I can recall many incidents where those who were pious, religious and of good character lost all their good qualities because they kept company and associated with an inappropriate circle of friends. I have also seen others who were drowning in sin and evil, who underwent a complete revolution in their lives after adopting the company of a pious person of huge moral standards.
