5 Namaz In Quran
Quran has all the details about prayer, including Jumma prayer. It describes details of Wudu and which direction to face for prayer. How to go to Rakuh and Sajdah. But the only two things missing is number of Rakahs in each prayer and anything specific to recite. Those details come from Sunnah. It seems to me that if someone had only access to Quran and the person sincerely wanted to pray, he could perform a rudimentary prayer based only on information from Quran.
