Surah 3 (chapter of quran) discusses the birth if Jesus and the the prophets before, who were given Torah and the other revelations. As I’ve understood they are considered true and from the same divine source, however have been muddied over time and hence the last and complete revelation is needed and given via the prophet Mohammed.
Then after his death, people were divided between whether to follow his divine bloodline (Shia) or his way of life (Sunnah) and they tried to capture all information about his life and teachings which were not in Quran (Hadith). The 5 daily prayers for example are not explicitly mentioned in the quran.










Thanks for the tip!
