UNDESIRABLE NAMES SHOULD BE CHANGED
Aishah RA reports that Rasulullah SAW used to change the unpleasant names of people and replaced them with good names.
Abdullah bin Umar RA relates that one of his sisters was named Aasiyah (disobedient). Rasullah SAW changed it to Jameelah (beautiful).
Zainab RA says that I had been named Birrah (pious). Rasulullah SAW then said: "Do not claim piety, for Allah knows best who amongst you are pious. Name her Zainab!"
NAMES MAY INFLUENCE THE LIVES OF PEOPLE
Sa'eed ibn Musayib RA relates from his father that his grandfather went to Rasulullah SAW and was asked: "What is your name?" He replied: "Hazn" (sorrow). Rasulullah SAW said: "You are Sahl." (contended). He replied: "I will not change the name my father had given me." The narrator says that thereafter sorrow continually remained with them.
KEEP AWAY FROM NAMES IMPLYING SHIRK
As Muslims, we should always abstain from keeping names implying any elements of Shirk, like adjoining the word 'Abd' (servant) to names or epithets other that those of Allah Ta'ala.
Rasulullah SAW also forbade keeping pompous and self-glorifying names, for this reveals arrogance and haughtiness - human elements most abhorred by Allah Ta'ala.
PROTECT THE DIGNITY OF YOUR IDENTITY AND FAITH
Muslims should always have dignity and protect their identity and faith. Nowadays, to conceal his/her identity, it is common practice for a person to "westernise" his name, like substituting Yusuf with Joe or Joseph, Uzair with Ozzie, Ridhuan with Ricky and even Muhammad with Mo.
Efforts to distort such beautiful names merely reveal an un-Islamic and sacreligious attitude. Remember, there exists behind each Islamic name an Islamic spirit and meaning, which, when distorted, is ruined. For example, there is intended love for the Prophet of Islam, and barakah when naming a child Muhammad. But when Muhammad is called Mo, this spirit of love for Rasulullah SAW and the acquiring of barakah by such a name is shattered. Should we not then refrain from such sacreligious practices?
May Allah Ta'ala guide us so that we may realise the beauty and uniqueness of the religion of Islam propounded by no other than the one who is the best of Allah's creations - Rasulullah SAW.
