Is the adhan and iqamah prescribed in the ears of a newborn?

Question:
What is the ruling regarding the adhan and iqamah in the child's ear when he reaches seven days? What is the benefit of that?

Answer:
It is reported in some hadiths that the adhan is called in the right ear and the iqamah is called in the left ear. There is some weakness in their chains, but it is a practice of the Muslims. So whoever does that, there is nothing wrong with it, and whoever leaves it, there is nothing wrong with it. Calling the adhan in the right ear and the iqamah in the left ear on the seventh day, and naming him, this is recommended according to a group of scholars.
It came in a hadith narrated by al-Tirmidhi, which he graded as authentic, that the Messenger (peace and blessings be upon him) used to call the adhan in the baby's right ear. It came in another hadith that he used to call the iqamah in the left ear. 'Umar ibn 'Abd al-'Aziz and a group of scholars said that this benefits the child. A group of Muslims have followed this practice, and whoever leaves it, there is nothing wrong with it. It was reported from the Prophet (peace and blessings be upon him) that he named his son Ibrahim when he was born, and it was not mentioned that he called the adhan in his right ear and the iqamah in his left. This indicates leniency. Whoever does that, there is nothing wrong with it, and he has done well, and if he leaves it, there is nothing wrong with it.
