Sahih International
They have no knowledge of it, nor had their fathers. Grave is the word that comes out of their mouths; they speak not except a lie.
Abdul Haleem
They have no knowledge about this, nor did their forefathers––it is a monstrous assertion that comes out of their mouths: what they say is nothing but lies.
Mohsin Khan/Hilali
No knowledge have they of such a thing, nor had their fathers. Mighty is the word that comes out of their mouths [i.e. He begot (took) sons and daughters]. They utter nothing but a lie.
Taqi Usmani
while they have no knowledge about it, nor had their fathers. Grave is the word that comes out of their mouths. They say nothing but lie.
Pickthall
(A thing) whereof they have no knowledge, nor (had) their fathers, Dreadful is the word that cometh out of their mouths. They speak naught but a lie.
Pickthall
No knowledge have they of such a thing, nor had their fathers. It is a grievous thing that issues from their mouths as a saying what they say is nothing but falsehood!
