Zakarīyā — the prophet Zechariah

Used sign language for three days:

  • He said, "My Lord, make for me a sign." He Said, "Your sign is that you will not [be able to] speak to the people for three days except by gesture. And remember your Lord much and exalt [Him with praise] in the evening and the morning. 3:41
  • [Zechariah] said, "My Lord, make for me a sign." He said, "Your sign is that you will not speak to the people for three nights, [being] sound." So he came out to his people from the prayer chamber and signaled to them to exalt [ Allah ] in the morning and afternoon. 19:10-11
