قَالَ كَذَٰلِكِ قَالَ رَبُّكِ هُوَ عَلَيَّ هَيِّنٌ ۖ وَلِنَجْعَلَهُ آيَةً لِّلنَّاسِ وَرَحْمَةً مِّنَّا ۚ وَكَانَ أَمْرًا مَّقْضِيًّا (21)
(19:21) The angel replied, "So shall it be. Your Lord says, `This is an easy thing for Me to do, and We will do so in order to make that boy a Sign for the people *15 and a blessing from Us, and this must happen."
*15) The word "So shall it be" are very significant as has been stated in E.N. 6. The plain meaning is this: "A pure son shall be born to you just as your Lord has decreed, even though no man has touched you. " The same was the response to prophet Zachariah as stated in v. 9 above. And it is a sheer perversion to interpret it as: "So shall it be that a man will touch you and a son will be born to you." For, if it were to mean: "You will bear a son like all other women of the world," the subsequent two sentences: "Your Lord says, 'This is an easy thing for Me to do, and We will make that boy a Sign for the people'," would have become meaningless: Had this birth been an ordinary birth like the birth of every other child, there would have been no occasion to boast: "It is an easy thing, and that it will be made a Sign (miracle). This will be so because the child will speak in the cradle. "
