[He was told], "O Zechariah, indeed We give you good tidings of a boy whose name will be John. We have not assigned to any before [this] name."
The Saheeh International Quran Translation
يَٰزَكَرِيَّآ إِنَّا نُبَشِّرُكَ بِغُلَٰمٍ ٱسْمُهُۥ يَحْيَىٰ لَمْ نَجْعَل لَّهُۥ مِن قَبْلُ سَمِيًّا[He was told], "O Zechariah, indeed We give you good tidings of a boy whose name will be John. We have not assigned to any before [this] name."
