قَالَ رَبِّ اجْعَل لِّي آيَةً قَالَ آيَتُكَ أَلَّا تُكَلِّمَ النَّاسَ ثَلَاثَ لَيَالٍ سَوِيًّا
[19:10]
He said: My Lord! give me a sign. He said: Your sign is that you will not be able to speak to the people three nights while in sound health.
(Zakariya) said: "O my Lord! give me a Sign." "Thy Sign," was the answer, "Shall be that thou shalt speak to no man for three nights, although thou art not dumb."
He said: My Lord! Appoint for me some token. He said: Thy token is that thou, with no bodily defect, shalt not speak unto mankind three nights.
