When you are reciting the Qur'an or the Duas of Ahlulbayt and you don't know the meaning will your prayers be answered? Or should we always read the translation instead?
Yes, it will be answered with out any doubt whether you recite in Arabic text or read the translation. Allah (SWT) knows our intentions and needs and He listens to every sincere believer who supplicates and seeks from him.
Quran is from Allah (SWT) and Du'a is from the Prophet (SAWA) and Ahlul Bayt (AS) and it is in Arabic for every Muslim to recite and supplicate whether he knows the exact meanings or not. There is no doubt that it is accepted by Allah (SWT).
Wassalam.
