Sahih al-Bukhari Book 9, Hadith 53
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).
Anas bin Malik said, "The Prophet (ﷺ) and Zaid bin Thabit took the 'Suhur' together and after finishing the meal, the Prophet (ﷺ) stood up and prayed (Fajr prayer)." I asked Anas, "How long was the interval between finishing their 'Suhur' and starting the prayer?" He replied, "The interval between the two was just sufficient to recite fifty 'Ayat." (Verses of the Qur'an).
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.
