ANSWER:

You can make Dua in the sujood of any prayer providing you don’t know how to say it in Arabic. Singling out the last sujood is baseless as you can make it in the sujood of any prayer or right before tasleem.

Can you please explain if we can make dua in salah, is it permissuble to only do so in the sunnah salah and to avoid making dua in the last sajood of sunnah salah? is there any basis to this?
