How can we convince the anti-Sunnah or Quraniyyoon about the Sunnah?
There is major work done by Azami, Mustafa Al-Azami. One of my teachers in Riyadh, it was his PhD. Thesis, ‘Studies in Early Hadeeth Literature’. The argument for authenticity of hadeeth literature, reject the arguments that it was written long after Prophet (ﷺ). He (ﷺ) has outlined with all of the evidence, the argument of authenticity of hadeeth literature; he deals with issue of Prophet (ﷺ) instructing in beginning of Islam, prohibiting writing, in order to protect the Qur'an and prevent confusion between the Qur'an and Hadeeth.
So we have to look at both sides, we have to bring evidences that clarify in both sides. As the Qur'an does not contradict itself, Sunnah doesn’t either, the authentic Sunnah. The contradiction maybe be apparent in the sense that it is generalities or specific circumstances, where Prophet (ﷺ) had said,
‘One should not pray after fajr until sunrise and after asr until sunset.’ 
So here is an apparent contradiction. Aisha (رضى الله عنها) asked him (ﷺ), why he (ﷺ) was praying after Asr, so he (ﷺ) clarified saying,
"these are not prayers which he (ﷺ) did, what he (ﷺ) felt like praying, ‘which are from my regular prayer of sunnah prayer, which I was unable to pray as a delegation came to see me’. 
If there is no instruction, which is coming from ourselves, no, then no, don’t pray. It is not contradiction, one was a general rule and other was specific clarification.
