How to offer Salah if one does not speak Arabic well?
If a Muslim can learn Arabic, they must do so in order to say the Adhkar (recitation, invocations and Remembrances said at certain times on a regular basis) of Salah such as Qur’an, Takbir (saying: "Allahu Akbar [Allah is the Greatest]") and supplications. If they can not learn Arabic, they can offer Salah according to their condition and recite the Adhkar in their own language. As for reciting the Qur’an, it is overlooked in such a case because they can not recite it in Arabic. Allah (Exalted be He) says:
Allâh burdens not a person beyond his scope.
The Qur’an can not be recited in any language other than Arabic.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
