For your information, Allah only revealed the Quran, not fabricated Ahadith or Sunnah.
Dear wake up pak sb, it is true that Allah only revealed the quran for purpose based proper guidance of mankind but the quran cannot be acted upon without making purpose based proper sense of its text in its own proper context. This is where others can help us and they do help us otherwise we will still be as we were when we were born into this world.
In my posts on other threads I have made it absolutely clear that each and every human being needs 100% help and support of others to come into this world and to survive. Babies do not educate and train themselves as soon as they are born others bring them into this world and help them gain education, training and skills. All we need to judge is whether that education and training as well as the skills we gain lead us in the right direction which helps us live our lives better and better or they lead us in the wrong direction whereby we end up harmed, ruined and destroyed by hands of each other. So any individual piece of information needs to be judged to see whether it should be accepted or rejected in light real world realities. The idea about wholesale rejection of human produced and collected information which they have passed down our generations is not acceptable at all. Even the quran we have has come to us through other people in this world.
The second criterion for accepting and rejecting human produced information is the quran. Anything that goes against the quran is not acceptable at all no matter what but the condition is that the quranic text itself must be first understood purposefully properly in light of real world realities. If the quranic text itself is not understood purposefully properly in light of real world realities in the first place then how can anyone reject any other information about anything according to the quran?
This is why we cannot reject even normal human historical account let alone totally reject reports about the prophet and messenger of God till we understand all these things purposefully properly in light of real world realities as well as in light of the quran and then in light of each other purposefully properly.
Hopefully my explanation makes sense.
Regards and all the best.
