Supplication and dua to Allah

وَإِنِّى خِفْتُ ٱلْمَوَٰلِىَ مِن وَرَآءِى وَكَانَتِ ٱمْرَأَتِى عَاقِرًا فَهَبْ لِى مِن لَّدُنكَ وَلِيًّا

And indeed, I fear the successors after me, and my wife has been barren, so give me from Yourself an heir

قَالَ رَبِّ ٱغْفِرْ لِى وَهَبْ لِى مُلْكًا لَّا يَنۢبَغِى لِأَحَدٍ مِّنۢ بَعْدِىٓ ۖ إِنَّكَ أَنتَ ٱلْوَهَّابُ

He said, "My Lord, forgive me and grant me a kingdom such as will not belong to anyone after me. Indeed, You are the Bestower."
