‘Abdullah
Hafiz ‘Asqalaani (rahimahullah) says that the name of the father of Rasulullah (sallallahu ‘alaihi wasallam) was ‘Abdullah. He has also mentioned that there is no difference of opinion regarding this fact.
The name ‘Abdullah is one of the names which is most beloved to Allah Ta‘ala, as a Hadith states that two names are most dear to Allah Ta‘ala; ‘Abdullah and ‘Abdur Rahmaan. The reason for this is that the name “Allah” is the Ism-ul-A‘zam (the supreme name of Allah). Hence, on account of the name ‘Abdullah (slave of Allah) being attributed directly to the Ism-ul-A‘zam, it is one of the most beloved names.
It would not be surprising if when ‘Abdullah was born, his father, ‘Abdul Muttalib, was divinely inspired by Allah Ta‘ala to name this blessed son with a name which is most beloved to Allah Ta‘ala.
