Not only are his intentions pure, but he's delivered very beneficial islamic lectures. Let me show you a few:
These are simple non-controversial lectures. He's simply talking about the purpose of life, and how the media has maligned islam, and to get a proper perspective.
I love how he raised the standards for islamic lectures. The brother rents out a hall, comes prepared with a memorized speech. He has amazing speech skills. His points are clear and digestible. He's not afraid of what to say and knows how to defend himself from attacks.
I salute the man.
You're against the scientific miracles lecture?
That's one of my favourite lectures!!
You say it's all fradulent, what about this one?
==Surah Az Zumar Chapter 39 Verse 21==
“Seest thou not that Allah sends down rain from the sky, and leads it through springs in the earth? Then He causes to grow, therewith, produce of various colours: then it withers; thou wilt see it grow yellow; then He makes it dry up and crumble away. Truly, in this, is a Message of remembrance to men of understanding.”
The quran was the first text in history to definitely say that rainwater is what fills aquifers in the ground. The first time that other people confirmed this was by french scientists in 18th century believe it or not.
"Aspects of groundwater origin were considered in many projects and philosophic works of the ancient Greek and Roman philosophers (Miletsky, Plato, Aristotle, Kar, Seneka, Pollio etc). The first quantitative concepts of groundwater formation due to infiltration of atmospheric precipitation were formed by French scientists P. Perro and E. Marriott in the middle of the eighteenth century based on the study of water balance in the Seine River"
