(201) بَابُ الْمُسْتَبَّانِ شَيْطَانَانِ يَتَهَاتَرَانِ وَيَتَكَاذَبَانِ
'Iyad ibn Himar reported that the Messenger of Allah, may Allahbless him and grant him peace, said, "Allah has revealed to me that youshould be humble so that none of you will oppress anyone else and noneof you will disdain another.' I said, 'Messenger of Allah, what do youthink I should do when a man reviles me in a low assembly and then I answerhim back? Do I incur any wrong action in doing that?' He replied, 'Twomen who revile one another are two shaytans who accuse one another anddeny one another.'"'Iyad said, "I was at war with the Messenger of Allah, may Allah bless him and grant him peace, and I gave him a she-camel before I became Muslim. He said, "I dislike the froth of the idolaters."
