However selecting names should be pursuant to some Islamic rules that will be stated below.
What names are not allowed in islam. If however a person does not know who his or her father is and it is impossible to find out then. As per Wikipedia he was also named Abd al-Rahman by Muhammad PBUH. Basmala or Bismillah.
If you are a Muslim convert you do not have to change your name unless your current name has a meaning that is against Islam for example names of pagan deities. However adding an Abd is fine. Names such as Noor al-DeenNuruddin Diya al-DeenZiauddin Shams al-Deen Sayf al-Islam Noor al-Islam Shams al-Islam Shihaab al-Deen and Dhahab al-Deen because of the great status attached to the words al-Deen and Islam.
The wrong nicknames were calling a person Dumb Stinky Shorty etc but here we will talk about the names which are allowed such as Abu Hurayrah whose real name was Ad-Dawsi Alzahrani the nicknames to him was given by Muhammad PBUH. From the names which should also be avoided are the names of tyrants and despots like. Islam is very concerned with honor life and religion by imposing death sentence on those who disturb it such as committing adultery murder and apostasy.
Using foreign names such as Turkish Persian Berber etc. Often I hear that such names are not allowed in Islam because those are qualitative names of Allah and we as human cannot expect those within ourselves. It is just one of the best ways to state in a name your religious identity.
Likewise goes for women. Abdullah bin Umar narrated that the Prophet of Allah said. Yes you can change your name according to the consensus of scholars provided that the new name does not have a bad meaning.
Lets first learn two import terms 1. In addition naming our child Zalim oppressor Kalb dog Khinzir pig or Khaliq creator and any such names that are contrary to monotheism and pure Islamic values are also forbidden. There are no other creation who could surpassed Him from every aspect the example Rahim Rahman Kholiq etc.
