(Muhammad Assad)
11:42 And it moved on with them into waves that were like mountains. At that [moment] Noah cried out to a son of his, who had kept himself aloof [from the others]: "O my dear son! Embark with us, and remain not with those who deny the truth!"11:42
(Yousaf Ali)
11:42 So the Ark floated with them on the waves (towering) like mountains, and Noah called out to his son, who had separated himself (from the rest): "O my son! embark with us, and be not with the unbelievers!"11:42
