-Quality vs Quantity-

There are some people who like to say that certain Ustaz / Ustazah is good because of how many likes they get on facebook. Not to put down those Ustaz / Ustazah but is it not that we should evaluate a certain Ustaz / Ustazah on :
1. Whether their teaching is based on Quran and Sunnah ?
2. Their akhlak when teaching ?
3. Whether when they give certain fatwa they come out with reference for you in order for you to do more research and not telling other that it is that Ustaz / Ustazah who tell ?

Think back my dear friends on what are you evaluating on a particular Ustaz, the Quantity of likes or the Quality of the Ustaz / Ustazah.
