who is it who has made the earth a place of resort and has caused rivers to flow in its midst and has placed upon it firm mountains and has placed a barrier between two masses of water? is there any god associated with allah ? nay but most of them do not know.
أمن جعل الأرض قرارا وجعل خلالها أنهارا وجعل لها رواسي وجعل بين البحرين حاجزا أإله مع الله بل أكثرهم لا يعلمون
