With the grace of Almighty Allah we have been blessed with baby girl after 3.5 years .Family members have been telling that we need to keep one name (Azaan name) immediately after reciting the azan on baby ear (i.e. at the time of birth). This name will be called at the time of Hashr. However, when I enquired with one Alim I was told that we can keep the name in 7 days. There is nothing like Azaan name and not mandatory to keep the name immediately after reciting azan. How far is this correct?
It is mustahab to name the baby after seventh day and do aqiqah.

It is not necessary to name after calling azan in the ears likewise ‘Azan’ is not a name. Alim sahib is right.
Allah (Subhana Wa Ta’ala) knows Best
