What is the ruling on initiating and returning the greeting of Salaam in a language other than Arabic, and is it permissible to worship through Allah's Most Beautiful Names in a language other than Arabic when one is able to pronounce them in Arabic?

Initiating a greeting in a language other than Arabic is permissible for one who is capable of greeting in Arabic, and it is sufficient to respond in a language other than Arabic. However, responding to a greeting from someone who used the prescribed wording is not sufficient with anything other than the prescribed wording for one who is capable of it. Scholars have agreed that for someone who has initiated a greeting, only a greeting suffices as a response. They have differed regarding one who offers a salutation using words other than the prescribed greeting. The correct view is that greeting in a non-Arabic language is permissible and responding to it is obligatory if the addressee understands it. As for what is meant to be an act of worship with its specific wording, it depends on the prescribed wording if one is capable of it, and it is obligatory to learn the words intended for worship, such as Al-Fatiha and Takbirat Al-Ihram. What is intended for both its wording and meaning may not be translated. What is intended for its meaning without its specific wording may be translated. As for obligatory invocations (adhkar), they may not be translated for one who is capable, but they may be translated for one who is incapable.
