Аль-Анбия 21:69–73

قُلْنَا يَا نَارُ‌ كُونِي بَرْ‌دًا وَسَلَامًا عَلَىٰ إِبْرَ‌اهِيمَ (We said, "0 fire, be cold and safe for Ibrahim." - 21:69) As stated above, one explanation of the fire becoming cool and comfortable for Sayyidna Ibrahim (علیہ السلام) could be that it ceased to be fire and changed into a pleasant breeze. However, the more plausible explanation is that the fire remained as fire but did not touch the body of Sayyidna Ibrahim (علیہ السلام) ، although it burnt other things around him, so much so that it even burnt down the rope which bound him.

According to some historic versions he remained in the fire for seven days and used to recall that those seven days were the most comfortable time of his entire life. (Mazhari)

وَنَجَّيْنَاهُ وَلُوطًا إِلَى الْأَرْ‌ضِ الَّتِي بَارَ‌كْنَا فِيهَا لِلْعَالَمِينَ

And We rescued him and Lut towards the land We blessed for all the worlds. - 71

That is, We delivered Sayyidna Ibrahim and Sayyidna Lut (علیہ السلام) from the land ('Iraq) where Namrud ruled and sent them to the peaceful land of Syria where our bounties were in abundance, not only for the locals but for the people of the world. Syrian land abounds both inwards and outwards bounties of Allah Ta ala. Inward bounties in the sense that many prophets were born in this land, and outward bounty in the sense that it has a moderate climate and is full of natural beauty with greenery, springs and streams all around and sustains a large variety of vegetation, fruits and flowers.

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'.
