Calling the Adhan and Iqamah in the ear of a newborn at birth
The Iqamah being said is not established at all, because the hadith that mentions it is not fit to be used as evidence, as narrated from Hussain ibn Ali (may Allah be pleased with him) that the Prophet ﷺ said:
من ولد له ولد فأذن فى أذنه اليمنى وأقام فى أذنه اليسرى لم تضره ام الصبيان
“Whoever has a child born to him, and calls the adhan in his right ear and the iqamah in his left ear, the affliction of Umm al-Sibyan will not harm him.”
Also, the report of Umar ibn Abd al-Aziz (may Allah have mercy on him) in this regard is not authentic either.
Furthermore, the narration regarding calling the adhan is also weak; in its chain, there is disagreement about the reliability of the narrator Asim ibn Ubaydullah.
However, on the basis of other corroborating evidence, this hadith reaches the level of hasan.
It is narrated from Abu Rafi’ (may Allah be pleased with him) that he saw the Messenger of Allah ﷺ:
أذن فى أذن الحسن بن على حين ولدته فاطمة بالصلاة
“When Fatimah (may Allah be pleased with her) gave birth to Hasan ibn Ali (may Allah be pleased with him), the Prophet ﷺ called the adhan in his ear like the adhan that is called for the prayer.”
(Abd al-Rahman Mubarakpuri) This hadith is weak, but it is strengthened by the narration of Hussain ibn Ali (may Allah be pleased with him), which was narrated by Imam Abu Ya’la al-Mawsili and Imam Ibn al-Sunni.
(Tirmidhi) This hadith is hasan sahih, and it is acted upon.
The continuous and inherited practice of the Ummah also makes it fit to be used as evidence.
(Ibn al-Qayyim) He quoted the hadith of Abu Rafi’ (may Allah be pleased with him) in his book Zad al-Ma’ad.
It should be noted that there is no fixed time for this adhan; whenever a Muslim is able to do so, he may call the adhan.
Two adhans for Friday are not established; the detailed explanation will come in the chapter “باب صلاة الجمعة“.
