Hi,
You have raised a good point. But quoting verses and hadith adds to more weightage of the topic and can win more marks. As we are to quote relevant verse and hadith for each topic. The common method to quote a verse or hadith is: The Holy Quran says: "----------" and write the translation of the relevant verse, (without cramming the para, sura & the verse number) and similar for hadith.
Quoting verses this way is better than not, and it will add value to your topic.
Best of luck.

Thanks
