Allah said, {Those who reject Our Ayat, We shall gradually seize them in ways they perceive not} meaning, the doors of provisions will be opened for them and also the means of livelihood, in this life. They will be deceived by all this and think that they are on the correct path. Allah said in another instance, {[So, when they forgot (the warning) with which they had been reminded, We opened for them the gates of every (pleasant) thing, until in the midst of their enjoyment in that which they were given, all of a sudden, We took them (in punishment) , and lo! They were plunged into destruction with deep regrets and sorrow. So the root of the people who did wrong was cut off. And all the praises and thanks are to Allah, the Lord of all that exists]}(quran/6/44-45). Allah said here, {And I respite them} prolong what they are in, {certainly My plan is strong} and perfect.
{184. Do they not reflect? There is no madness in their companion. He is but a plain warner .}

Allah said, {Do they not reflect ?} ‘those who deny Our Ayat,’ {there is not in their companion }, Muhammad, {madness} Muhammad is not mad, rather, he is truly the Messenger of Allah, calling to Truth, {but he is a plain warner}, and this is clear for those who have a mind and a heart by which they understand and comprehend. Allah said in another Ayah, {[And (O people) your companion is not a madman.]}(quran/81/22) Allah also said, {[Say : "I exhort you to one (thing) only, that you stand up for Allah's sake in pairs and singly, and reflect, there is no madness in your companion . He is only a warner to you in face of a severe torment ."]}(quran/34/46) meaning, 'I ask you to stand for Allah in sincerity without stubbornness or bias,’ {in pairs and singly} [34:46] individuals and in groups, {and reflect} [34:46], about this man who brought the Message from Allah, is he mad? If you do this, it will become clear to you that he is the Messenger of Allah in truth and justice. Qatadah bin Di‘amah said, “We were informed that the Prophet of Allah once was on (Mount) As-Safa and called the Quraysh, subtribe by subtribe, proclaiming, "O Children of so-and-so, O Children of so-and-so!" He warned them against Allah's might and what He has done (such as revenge from His enemies ) . Some of them commented, 'This companion of yours (Prophet Muhammad) is mad; he kept shouting until the morning?’ Allah sent down this Ayah, {Do they not reflect? There is no madness in their companion. He is but a plain warner} [7:184].’”
