What was the amount of time that elapsed between the Prophet Muhammad (saw) taking Suhur and beginning the morning prayer?
 Narrated Anas:                     Zaid bin Thabit said, "We took the "Suhur" (the meal taken before dawn while fasting is observed) with the Prophet and then stood up for the (morning) prayer." I asked him how long the interval between the two (Suhur and prayer) was. He replied, 'The interval between the two was just sufficient to recite fifty to Sixth 'Ayat."
