Each word's meaning and sound
Zechariah (peace be upon him) said: “My Lord, give me a sign I can feel content with and which will show that the glad tiding given to me by the angels has been attained”. He said: “Your sign of having attained what you were given glad tidings of is that you will not be able to speak to people for three days, not due to any illness, but rather you will be sound and well”.
