Allah tells; رَبَّنَا إِنَّكَ تَعْلَمُ مَا نُخْفِي وَمَا نُعْلِنُ وَمَا يَخْفَى عَلَى اللّهِ مِن شَيْءٍ فَي الَارْضِ وَلَا فِي السَّمَاء"O our Lord! Certainly, You know what we conceal and what we reveal. Nothing on the earth or in the heaven is hidden from Allah." Ibn Jarir At-Tabari said about the ayah, رَبَّنَا إِنَّكَ تَعْلَمُ مَا نُخْفِي وَمَا نُعْلِنُ (O our Lord! Certainly, You know what we conceal and what we reveal),"meaning, `You know the intention behind my supplication for the people of this town, seeking Your pleasure in sincerity to You. You know all things, apparent and hidden, and nothing escapes Your knowledge on the earth or in heaven."'He next praised and thanked his Lord the Exalted and Most Honored for granting him offspring after he became old,الْحَمْدُ لِلّهِ الَّذِي وَهَبَ لِي عَلَى الْكِبَرِ إِسْمَاعِيلَ وَإِسْحَقَ إِنَّ رَبِّي لَسَمِيعُ الدُّعَاء
