Any names which is contrary to the way of the Qur’aan and Sunnah, is contrary to the custom of the Muslims.
The islamic NAMES like Ahmadollah/Ahmadullah, Mohamedollah/Mohamedullah, Ibrahimollah, Mosaollah, Isaollah.. are wrong and not allowed.
Explan:It is not allowed to add beside Names of People/Prophets/Angels the name of Allah. As Great Allah says in Quran "Sura 61-Assaf -..... اسْمُهُ أَحْمَدُ.... ۖ , ...his(Prophet Muhammad SAW) name is Ahmad....". So Ahmad/Mohamad SAW, Ibrahim, Adam, Isa, Ilias, Musa, Haroon,..... are the names of Prophets mentioned in Quran, This names can not be used with the name of Great Allah, because it will means
Ahmadollah/Ahmadullah => Ahmad/Mohamd of Allah
Nobody is of Allah. It is Shirk if you say Ahmad/Mohamad, Isa, Musa,.. of Allah. " لَمْ يَلِدْ وَلَمْ يُولَدْ / He neither begets nor is born." Quran Sura 110:3
It is somehow allowed to add some of Adjectives words mentioned in 99 Adjectivly-Names of Great Allah with name of Allah. Like Adjectiv-Name Hamed(praiseworthy) to add it with name of Great Allah =>Hameedullah(praiseworthy of Allah),
Who has these names like Ahmadullah, Mohamadullah,.. has to ask his father to correct it, if the father is not in live, has to ask his old person in his family/tribe to do it. If he is himself the oldst, then he has to change it and make it public, that the other people do not name their childeren like this.
