Can Muslims Use The Facebook, Especially When Non-Muslims Use It To Defame Islam?

Question

Using the Facebook and other social media platforms has both advantage and disadvantages. So, the ruling of using such tools depends on the way you use them and the time you dedicate for them. A Muslim should be wise and careful about the way he spends his/her time because on the Day of Judgement, two questions out of the four to be posed to him are related to time, namely, how he/she spent his/her time and how he/she spent his/her youth age. Therefore, we need to rationalize our usage of these platforms, benefit from their advantage and keep away from their negative aspects.
