Has it been narrated that the crow was going to say to the polytheists: (ghar ghar) then Allah made it say: (ghaq ghaq) in the story of the cave?

The crow is not mentioned in the narration of the Hijra (Prophet's migration). What has been mentioned about it is a fabrication by fabricators. Allah blinded the eyes of the disbelievers from the Prophet, peace and blessings be upon him, and his companion Abu Bakr, and He granted them victory, as evidenced by the Almighty's saying: "If you do not aid him - Allah has already aided him when those who disbelieved expelled him, he being the second of two; when they were in the cave and he said to his companion, 'Do not grieve; indeed Allah is with us.' Then Allah sent down His tranquility upon him and supported him with soldiers you did not see and made the word of those who disbelieved the lowest, while the word of Allah - that is the highest. And Allah is Exalted in Might and Wise."

It is also narrated in the agreed-upon Hadith on the authority of Anas ibn Malik that Abu Bakr said to the Prophet while they were in the cave: "O Messenger of Allah, if one of them were to look down at his feet, he would see us." The Prophet replied: "O Abu Bakr, what do you think of two with whom Allah is the third?"
