Duas from Surah Maryam

"My Lord, my bones have grown feeble and my head is aflame with grey, yet never have I been unblessed in my prayer to You… So grant me from Yourself an heir, who will inherit from me and inherit from the family of Ya'qub. And make him, my Lord, pleasing to You."

When to recite: for children late in life; when a supplication long goes unanswered — Zakariyya prayed for decades.
