Quran 19:5 from Surah Maryam on Divine Marvels.
وَإِنِّي خِفۡتُ ٱلۡمَوَٰلِيَ مِن وَرَآءِي وَكَانَتِ ٱمۡرَأَتِي عَاقِرٗا فَهَبۡ لِي مِن لَّدُنكَ وَلِيّٗا
English translation: And indeed, I [I] fear the successors after me after me and is my wife barren So give [to] me from Yourself an heir
Transliteration: wa-inni khif'tu al-mawaliya min warai wakanati im'ra-ati aqiran fahab li min ladunka waliyyan
