I asked other scholars about making dua in a language other than arabic in sajdah (prostration) and I was informed that it was valid and could be done. please comment based on quran and sunnah.

All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.

Whoever can supplicate in Arabic must not supplicate in another language in the prayer. ‘Umar, may Allah be pleased with him, proscribed the non-Arabs’ jargon (in the prayer).

Many scholars believe that Du‘aa in a language other than Arabic for those who are able to do it in Arabic is disliked; some of them even forbade it. But if the person does not speak Arabic, he can make Du‘aa in any other language. This is a common agreement among all the scholars.

For more benefit on making Du'aa’ (supplicating) and reading Quran in a language other than Arabic, please refer to Fataawa 84628, 97317, 81564, 81795, 88514, 90654, 90869, 123119, 83636, 318661 and 335503.

Allah knows best.
