What is the most preponderant of Imam Malik's statements regarding the ruling on the Adhan and Iqamah in the ear of a newborn after its birth, along with its evidence and the source of his opinion?

Imam Malik disliked the practice of calling the Adhan in one ear of the newborn and the Iqamah in the other, due to the absence of an authentic narration proving it. Conversely, some Maliki scholars and others, such as Imam al-Nawawi, recommended it. Al-Nawawi cited as evidence the hadith of the Prophet (peace be upon him) calling the Adhan in the ear of Al-Hasan ibn Ali, and he pointed out that people have customarily acted upon this. The preponderant opinion narrated from Malik is that he disliked it, whereas some of his companions and other scholars recommended it.
