Is it true what is said that on the twelfth of Rabi' al-Awwal, the sun emits all spectrum colors and sways left and right?

Scholars differed on whether the twelfth of Rabi' al-Awwal is the day of the Prophet's birth. Nevertheless, it is a day like any other, with no special characteristic. The descriptions of this day mentioned in the question are a devilish myth aimed at convincing people of the innovations of celebrating it and singling it out for acts of worship not sanctioned by Allah. These innovations were introduced by the Fatimids, who had six mawlids, one of which was the Prophet's Mawlid. Celebrating the Mawlid is a reprehensible innovation that was not practiced by the Messenger of Allah, peace be upon him, nor by his companions, nor by the Salaf. Ibn Taymiyyah stated that the Salaf did not do it despite the presence of what would necessitate it, and if it were good, they would have been more deserving of it than us. The perfection of love and veneration for the Prophet lies in following him, obeying him, adhering to his commands, and reviving his Sunnah.
