My question is .. Can we do recitation through Quran or by looking at any other source during namaz?
Kya hum namaz k dauraan Quraan se dekh k Surah ki tilawat kar sakty hain? Agar zabani yaad nhi toh

Your deeni sister

Answer :

In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
It is impermissible to read from the mushaf or any other source in salāt as this will invalidate the salāt.[i]
You should suffice with the surahs you have memorized. If you have not memorized any surah, then you should endeavor to memorize some surahs.   
And Allah Ta’āla Knows Best
