Surah 3. Aal-Imran
Ayah 40 - 41
40 قَالَ رَبِّ أَنَّىٰ يَكُونُ لِى غُلَـٰمٌ وَقَدْ بَلَغَنِىَ ٱلْكِبَرُ وَٱمْرَأَتِى عَاقِرٌ ۖ قَالَ كَذَٰلِكَ ٱللَّهُ يَفْعَلُ مَا يَشَآءُ
41 قَالَ رَبِّ ٱجْعَل لِّىٓ ءَايَةً ۖ قَالَ ءَايَتُكَ أَلَّا تُكَلِّمَ ٱلنَّاسَ ثَلَـٰثَةَ أَيَّامٍ إِلَّا رَمْزًا ۗ وَٱذْكُر رَّبَّكَ كَثِيرًا وَسَبِّحْ بِٱلْعَشِىِّ وَٱلْإِبْكَـٰرِ
[40-41] Zacharias said, "Lord, how shall I beget a son now that I have grown very old and my wife is barren?" "Thus will it be,”40 was the answer. "Allah does whatever He wills." He said, "Lord, give me a Sign."41 "Your Sign is that you shall not (be able to) speak to anyone for three days but by gestures. During this period you should remember your Lord much and glorify His Name in the morning and in the evening."42
40That is, "Despite your old age and the sterility of your wife, Allah will bestow upon you a son."
41That is, "Give me a token to assure me beforehand of the birth of a son to an old man and a barren woman."
42The main object of this discourse is to make the Christians realize the error of their belief in taking Jesus for the son of God, and making him an object of worship. The extraordinary birth of John has been mentioned in the Qur'an to serve as .introduction to the subsequent argument against their wrong belief. The miraculous birth of Jesus could no more entitle him to Divinity than the extraordinary birth of John, brought about in the same family in a different and unusual way could entitle the latter to Divinity.
