In the terminology of Shari'ah, the basic issues of the whole Qur'an have been summarized in Surah Fatiha, therefore Surah Fatiha is called 'Ummul Quran'. Allah has not revealed anything in the Torah and the Injil like Surah Fatiha, the mother of the original Qur'an. This surah is the 8 verses recited in each rak'ah of the prayer and the great Qur'an which has been given to me. (Sunan Nasai , Tirmidhi , Mishkat: 2142)
