Tasmiyah (Naming The Child)
It is from the teachings of the Messenger of Allah, that each member of the family be given a good name. Those who ask Allah to give them children should also ask Allah to make these children among the followers of the Prophet Muhammad and adherents to his Sunnah. It is an obligation upon the parents that their child be given a good name. Some Ahadeeth indicate that the child is to be named on the seventh day along with Aqeeqah. However, the Prophet also named children on the day of their birth, as proven by other narrations. There is no harm if the child is named before the seventh day, but if the naming has not been done, and then the child should be named on the seventh day.
Naming a child with a beautiful and honourable name is very important. The Prophet always chose names with good and beautiful meanings, even telling people to change their names if they had unpleasant meanings.
Narrated by Abu Musa (RA)" a son was born to me and I took him to the Prophet who named him Ibrahim, did tahneek for him with a date, invoked Allah's blessing upon him and returned him to me.

Usaman Ibn Akhdari (RA) said, a man called Asram (harsh, severe, cut off) was among those who came to the Apostle of Allah. The Apostle of Allah said "what is your name?" he replied "Asram" He said "no, you are Zu'rah". (which means, has been taken or derived from crop, or to sow seed).
