(25:51) And if We had willed, We could have sent into every city a warner. (25:52) So do not obey the disbelievers, and strive against them with the Qur`an a great striving. (25:53) And it is He who has released [simultaneously] the two seas, one fresh and sweet and one salty and bitter, and He placed between them a barrier and prohibiting partition. (25:54) And it is He who has created from water a human being and made him [a relative by] lineage and marriage. And ever is your Lord competent [concerning creation]. (25:55) But they worship rather than Allah that which does not benefit them or harm them, and the disbeliever is ever, against his Lord, an assistant [to Satan]. (25:56) And We have not sent you, [O Muhammad], except as a bringer of good tidings and a warner. (25:57) Say, "I do not ask of you for it any payment - only that whoever wills might take to his Lord a way."
