Bismillahir Rahmaanir Raheem
Respected questioner,
Sajdah(prostration) will be Wajib after reading a translation of a verse of Sajdah. [1]
The Ahnāf are of the opinion that the translation of the Quran is ‘Quran min wajhil ma’naa’ which is why one must have wudhu to touch the translation of the Quran also. [2]
