Adhan in a newborn’s ear

Question: Is giving the Adhan in a newborn’s ear an authentic Sunnah, and is there any basis for saying the Iqamah in the other ear?

Praise be to Allah

Summary:
There is a difference of opinion among scholars regarding giving the Adhan in the ear of a newborn. Some scholars, such as Sheikh Ibn Baaz and Ibn Qayyim, consider it recommended (mustahab) due to potential benefits, while others, including Sheikh Nasiruddin al-Albani, view it as a weak practice due to the lack of strong evidence. As for saying the Iqamah in the left ear, there is unanimous agreement among scholars that this practice is not supported and should not be done.

Detailed Answer:
The primary narration on this subject is found in Sunan Abu Dawood and Sunan al-Tirmidhi (Vol. 5, Hadith 1514), where it is reported that the Prophet Muhammad (peace and blessings be upon him) gave the Adhan in the ear of his grandson, Hasan ibn Ali, at birth. Scholars hold differing views on the authenticity of this Hadith. Some, like Sheikh Ibn Baaz and Ibn Qayyim, suggest that the Adhan may be given, considering it mustahab, as the first words a child hears are those that remind of Allah and His Prophet. On the other hand, Sheikh Nasiruddin al-Albani and others argue that the Hadith remains weak even when corroborated with other narrations, deeming it unreliable for establishing Sunnah.

Regarding the Iqamah in the left ear, scholars universally agree that this lacks basis in any authentic Hadith and should not be practiced. Sheikh Ibn Baaz explicitly clarifies that while there is a basis for discussing the Adhan in ear of a new born, the Iqamah practice in ear of new born  is weak and unanimously discouraged.
