Why do some Muslim pray Zuhur/Asr silently while Allah in [Al-Quran:17:110] says to pray in a moderate tone?

As-Salaumu Alaykum! Please provide proof from Al-Qur'an and/or saheeh hadith which support Zuhr and Asr prayers are to be prayed silently. There are two proofs that suggest that Muslims should read Zuhr, Asr and all other mandatory prayers in a audible range ## 1. Allah suggest that prayer be read in a moderate tone in [17:110] > Say, ‘Invoke “Allah” or invoke “the All-beneficent.” Whichever [of His Names] you may invoke, to Him belong the Best Names.’ **Be neither loud in your prayer, nor murmur it, but follow a middle course between these.** [Al-Qur'an, Surah 17:110 ] Hence Muslims are directly instructed by ALLAH Subhana Wa Talla to read their prayers in a moderate audible tone ? I believe that Al-Qur'an prevails everything, while Sunnah clarifies. ## 2. [Sahih al-Bukhari #762] impiles that Prophet Mohamed (saw) recitation in Zuhr and Asr was audible It was narrated by Abdullah bin Abi Qatada that: > My father said, "The Prophet (ﷺ) used to recite Al-Fatiha along with another Sura in the first two rakat of the Zuhr and the `Asr prayers and at times a verse or so was audible to us." > >Reference : Sahih al-Bukhari #762 --- I have found NO RELIABLE HADITH which instructs Muslim to read Zuhur or Asr - silently. In fact contradicting ALLAH in 17:110 - would be a deviation from faith. So I kindly ask to provide dalil, proof, references to Al-Qur'an and/or reliable hadith on the basis of which Zuhur and Asr are conducted without audible recitation of Al-Qur'an.
