Some of them preferred to recite only the Fatihah of the Book, and some scholars said that there is no harm in adding a short surah to the mother of the Qur’an. Some of them said that there is no desirable timing in reciting the two rak’ahs of Fajr, and what I go to is that it be brief and shortened in completeness without timing, and the Fatihah is not. It is a must, for it is the essence of prayer in prayer, and whoever does not recite it in his prayer has not prayed, and the Sunnah has stated that they are both good, even if you are pressed for time.
