A person may speak a word which Allah, the Almighty, loves and is pleased with, like advising, directing, or teaching others, and he does not realize the level it reaches in terms of the pleasure of Allah, the Almighty, and because of that word Allah raises him to lofty ranks. Likewise, a person may speak a word that displeases Allah, such as backbiting, gossip, and slander, and it causes him to fall into Hellfire on the Day of Resurrection.
