39:41 Verily We have revealed the Book to thee in Truth for (instructing) mankind. He then that receives guidance benefits his own soul: but he that strays injures his own soul. Nor art thou set over them to dispose of their affairs.
Do not backbite one another, backbiting is when you make mention of someone in such a way that he would be displeased to hear it. (Abu Dawood & Tirmizi)
