Never encourage them to call you with ALLAH's name...ie Raouf, Malik, Latheef...
The accent of Allah SWT is
Al Raoof,
Al Malik,
Al Lateef not just Raoof,Malik and Lateef.If you look at the names of Prophet Muhammad SAW,there are a few names which are similar to Allah SWT's names.They are,
Awwal (The First) and
Aakhir (The last).Surely,Prophet Muhammad SAW is not Awwal neither the Last, just Last of the Prophets AS,so why Allah SWT gave him the same names without adding
Abdul before them ^o) And why not Muhammad SAW taught us to add
Abdul before them :embarrass
Another example is
Ali RA.Ali is also one of the 99 names of Allah SWT,so why did'nt Muhammad SAW asked him to call himself
Abdul-Ali.The reason is,if you look carefully,Allah SWT is
Al-Awwal,Al-Aakhir and Al-Ali and Muhammad SAW is
Awwal,Aakhir and Ali RA is just Ali not Al-Ali.
As im not Arab,neither i know this language,so im unable to explains whats the difference between Al-Awwal and just Awwal but i can say this for sure calling someone Awwal,Aakhir,Razik,Majid,Raoof,Ahad ......... is
Not a sin and not a claim to have the characteristics of Allah SWT.
P.S.
If any member here Know Arabic,do explain the difference between Al-Raoof and Just Raoof.I will be grateful :statisfie
