In the name of God who is Merciful towards all creation and Especially Merciful towards believers
Zachariah humbly and politely supplicated and reached out to God. He said, “ Oh, my Lord! I am now old and feeble, and my hair has turned white. I have always come to you with my needs and supplications. My Lord! I am worried about my family not having a spiritual guide and helper after me. My wife is barren so bestow upon me a child from Your presence who will be one of Your friends, an heir who inherits me and inherits from the house of Jacob.( Inheritance here is referring to continuing the legacy of prophethood and not wealth, etc.). And make him, my Lord, one with whom You are Well-pleased. (Quran, Maryam 2-6).
Zachariah was a great prophet and chosen by God. He never lost faith in God’s Mercy and always held his head down in front of God's greatness. It was for this reason that God always held him under his indefinite mercy. He wished for a child and so he asked God to make his wish come true. He asked for a child who would be pure and God's chosen, who would live life at the highest spiritual levels. God granted him his wish.
