· The Prophet, sallallaahu `alayhi wa sallam ( may Allah exalt his mention ), would teach his wives to guard their tongues:Due to the numerous harms of the tongue, the Muslim husband should instruct his wife and teach her how to guard her tongue and use it appropriately. Two of the most destructive diseases of the tongue which a husband should be especially wary of are backbiting and tale-bearing. The Prophet, sallallaahu `alayhi wa sallam ( may Allah exalt his mention ), was very keen to protect his wives from any such diseases and would immediately correct them and instruct them in this regard.‘Aa’ishah, may Allah be pleased with her, said, “I said to the Prophet sallallaahu `alayhi wa sallam ( may Allah exalt his mention ) ‘Such and such a matter of Safiyyah is sufficient for you (meaning that she was a woman of short stature).’ He sallallaahu `alayhi wa sallam ( may Allah exalt his mention ) said: ‘You have uttered a statement that would pollute the (entire) sea if it were mixed in it.’”
She, may Allah be pleased with her, further stated, “I once imitated a person in his presence and he said:‘I would never like to imitate anyone, even (if I was paid) such and such an amount (for doing so).’”[Abu Daawood and At-Tirmithi]
