Is it permissible for us to supplicate to Allah with names other than those mentioned in the Qur'an , such as the English word "God",
which they consider as the translation of the word Allah?
(Part No. 2; Page No. 236
Allah (Exalted be He) says:
And (all) the Most Beautiful Names belong to Allâh, so call on Him by them
Accordingly, Allah is to be supplicated with His established Names and Attributes mentioned in the Qur'an, and neglecting any others of which there was no solid evidence either in the Qur'an or the Sunnah. It is even preferable; rather Wajib (obligatory), to use the Arabic word if possible, because it is the language of the Qur'an and the Sunnah. However, if this is not within ability, it may be said in the language spoken by the said person, for Allah (Exalted be He) says:
Allâh burdens not a person beyond his scope.
May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
