Touching Quran without 'wudu'...my muslim friend who is very pious said to me that we should not give a quran to non-muslim which has 'arabic' text as non-muslims don't do 'wudu'

One of my friend is interested in Islam. I had advised him to buy a translation Quran. He bought one 'tamil translation' Quran (we are from Tamil-Nadu, India). That Quran has both arabic text and tamil translation. One of my muslim friend who is very pious said to me that we should not give a quran to non-muslim which has 'arabic' text as non-muslims don't do 'wudu'. But my friend keeps the quran with good respect and touches with clean. He even clean his private parts afetr urin (which is done only by muslims). But he doesn't know about 'wudu'. Now, my question is , 1) Do I have to stop him touching that quran? 2) Should I advise him to buy a quran which doesn't have arabic text? 3) Do I have to do kaffara?
