All perfect praise be to Allah, The Lord of The Worlds, and may His blessings and peace be upon our Prophet Mohammad and upon all his family and companions.

According to authentic Sunnah, it is desirable to call Athaan in the ear of the newborn as indicated in the Hadith narrated by Abu Rafi': "I saw the Messenger of Allah (PBUH) uttering the call to prayer (Adhan) in the ear of al-Hasan ibn Ali when Fatimah gave birth to him." {Atirmizi graded it as Hasan}. Moreover, it was narrated that this act of Sunnah was narrated by the righteous predecessors, such as Omar Bin Abd al-Aziz, as stated in the book [Mosanaf Abdulrazaak].

Consequently, Shafie jurists have stated that saying Athaan in the ear of the newborn is desirable, and this opinion was approved by the Hanbalie jurists, and was quoted by the Hanfie jurists from the Shafies. Ibn Abdeen stated: "We share this opinion because it is backed by an authentic Hadith. Therefore, any scholar can adopt it." {Rad al-Mohtar}. And Allah Knows Best.
