Lets assume all of us are looking for the right path to follow with all of our sincerity. In terms of our approached, we could be divided into three groups

1- Quran Only People (All religion is included in the Book).
2- Quran + Hadith People (The source of religion are Quran and the saying of the Prophet pbuh as recorded in the Hadith books).
3- Quran + Sunnah People (The source of religion are Quran and Sunnah, but not the Hadith books. Both sources are protected by God in the crowd. There is no dependency on Hadithes).

All the three groups put towards good points to the table.

I invite all of us to please take out some time and watch this video with open heart.
Dr Sahib is making some very interesting points here. If you agree then you can express your opinion. If you don't then please express your arguments.

At the end of the day, I believe in the eyes of God those will be successful who tried to search for the straight path with sincere efforts, irrespective if they found that path or not.
