But as for those who are bent on giving the lie to Our messages - We shall bring them low, step by step, without their perceiving how it came about: 182 And I respite them; certainly My Plan is strong. 183 Then do they not give thought? There is in their companion [Muhammad] no madness. He is not but a clear warner. 184 Or have they not considered the dominion of the heaven and of the earth, and what things God has created, and that it may be their term is already nigh? In what manner of discourse then will they after this believe? 185 Whoever Allah sends astray - there is no guide for him. And He leaves them in their transgression, wandering blindly. 186 They ask you, [O Muhammad], about the Hour: when is its arrival? Say, "Its knowledge is only with my Lord. None will reveal its time except Him. It lays heavily upon the heavens and the earth. It will not come upon you except unexpectedly." They ask you as if you are familiar with it. Say, "Its knowledge is only with Allah, but most of the people do not know." 187 Tell them: "I am not master of my own gain or loss but as God may please. If I had the knowledge of the Unknown I would have enjoyed abundance of the good, and no evil would have touched me. I am only a bearer of warnings and bringer of happy news for those who believe." 188
