Is it true that Azar spoke to our master Ibrahim (peace be upon him) after he emerged from the fire, saying to him: "Blessed is your Lord, O Ibrahim"?

"Yes, your Lord is your Lord, O Ibrahim" is a statement mentioned by a number of exegetes and narrators of the prophets' stories in connection with the verse: "We said, 'O fire, be coolness and safety upon Ibrahim.'" It was narrated on the authority of Abu Hurayrah that it was said by Ibrahim's father when he saw him in the fire, and some attributed it to Nimrod. It is among the Isra'iliyyat (Judeo-Christian traditions) that exegetes mention, and no one has authenticated it.
