It is narrated from Ikrimah (may Allah have mercy on him), he says that either Sayyiduna Ibn Abbas or Sayyiduna Ibn Umar (may Allah be pleased with them) invited the other. A slave girl was serving them, so (upon her mistake) one of them said to her: "O adulteress!" The other companion said: "Stop! If she is not punished for this accusation in this world, then in the Hereafter the punishment (for this slander) will be enforced." He said: "What do you say if she really is like that?" The other companion replied: "Allah Almighty does not like foul-mouthed and obscene speakers at all." Sayyiduna Ibn Abbas (may Allah be pleased with them) said: "Allah Almighty dislikes those who use foul language and speak obscenely."
