After the birth of prophet, Bibi Amina immediately sent someone to inform his grandfather ‘Abdul- Muttalib of the happy event.
Happily he came and, carried Muhammad Sallallahu Alaihi wasallam to Al-Ka‘bah, prayed to Allah and thanked Him.
‘Abdul-Muttalib called the baby Muhammad, a name not then common among the Arabs.Muhammad means who has been praised/praisedone/worthy to be praised. It is derived from root word Hamd.
Abdul-Muttalib circumcised him on his seventh day as was the custom of the Arabs.
