question #1 Sahih Muslim 723a, Book 6, Hadith 106 : What is the significance of performing two short rak’ahs before the Fard prayer at dawn?

Ibn ‘Umar reported that Hafsa, the Mother of the Believers, informed him that when the Mu’adhdhin became silent after calling (people) to the dawn prayer, the Messenger of Allah (ﷺ) commenced the dawn (prayer) when it dawned by observing two short rak’ahs before the commencement of the (Fard) prayer.
