19:10
قَالَ رَبِّ ٱجْعَل لِّىٓ ءَايَةً ۚ قَالَ ءَايَتُكَ أَلَّا تُكَلِّمَ ٱلنَّاسَ ثَلَـٰثَ لَيَالٍ سَوِيًّا
qāla rabbi ij'ʿal lī āyatan qāla āyatuka allā tukallima l-nāsa thalātha layālin sawiyyan
He said, ‘Give me a sign, Lord.’ He said, ‘Your sign is that you will not [be able to] speak to anyone for three full [days and] nights.’
[Zakariyyâ (Zachariah)] said: "My Lord! Appoint for me a sign." He said: "Your sign is that you shall not speak unto mankind for three nights, though having no bodily defect."
