Sahih al-Bukhari Book 9, Hadith 54
The believing women covered with their veiling sheets used to attend the Fajr prayer with Allah's
Apostle, and after finishing the prayer they would return to their home and nobody could recognize
them because of darkness.
I used to take the "Suhur" meal with my family and hasten so as to catch the Fajr (morning prayer) with Allah's Messenger (ﷺ).
Allah's Messenger (ﷺ) said, "Whoever could get one rak`a (of the Fajr prayer) before sunrise, he has got the (morning) prayer and whoever could get one rak`a of the `Asr prayer before sunset, he has got the (`Asr) prayer."
