Ibrāhīm

الْحَمْدُ للَّهِ الَّذِي وَهَبَ لِي عَلَي الْكِبَرِ إِسْمَاعِيلَ وإِسْحَاقَ إِنَّ رَبّـِي لَسَمِيعُ الدُّعَآءِ

39. “Praise be to Allah, Who has granted me in old age Ishmael and Isaac. Verily my Lord is the Hearer of the petition;”

Ishmael and Isaac are among the specific blessings of Allah, for: 1- They were born because of the prayers of the prophet of Allah, ‘Ibrahim. 2- They were born during the old age of their father. 3- They were both righteous children. 4- They headed their following chain of prophets. Incidentally, what is important is the issue of having righteous children, whether they are born by a female slave or else. (Ismael was born by a female slave and Ishaq was born by a free woman.)

At any rate, one’s children are gifts from Allah and nothing deters or serves as a hindrance for Allah’s Will and the Divine power; therefore, senility did not obstruct him from having children. The verse says:

“Praise be to Allah, Who has granted me in old age Ishmael and Isaac. Verily my Lord is the Hearer of the petition;”
