The Migration of Ibrahim to Ash-Sham (Greater Syria), accompanied by Lut

Allah tells us that He saved Ibrahim from the fire lit by his people, and brought him out from among them, migrating to the land of Ash-Sham, to the sacred regions thereof.

وَوَهَبْنَا لَهُ إِسْحَـقَ وَيَعْقُوبَ نَافِلَةً

وَوَهَبْنَا لَهُ إِسْحَاقَ وَيَعْقُوبَ نَافِلَةً (And We blessed him with Ishaq and Ya` qub as gift - 21:72) That is, Allah Ta` la had bestowed upon him the son Ishaq (علیہ السلام) as per his supplication and in addition to that a grandson Ya` qub (علیہ السلام) as a gift. This is why he is referred to as نَافِلَةً nafilah which originally means 'extra'.
