السلام عليكم و رحمة الله و بركاته I make recommended duas before tasleem in arabic, can I make duas that are not in arabic which I want in fard salah and how about in sujood? بارك الله فيك وجزاك الله خيرا

Ustadh AbdulAziz al-Haqqan
If you are able to make the du'a in Arabic, make it in Arabic. If you are not able, you may make it in your own language, in sujood and before the tasleem, in the obligatory and the voluntary prayer alike.
