Zaid bin Thabit said, "We took the Suhur with the Prophet ﷺ . Then he stood for the prayer." I asked, "What was the interval between the Suhur and the Adhan?" He replied, "The interval was sufficient to recite fifty verses of the Qur'an."  

تَسَحَّرْنَا مَعَ النَّبِيِّ ﷺ ثُمَّ قَامَ إِلَى الصَّلاَةِ قُلْتُ كَمْ كَانَ بَيْنَ الأَذَانِ وَالسَّحُورِ قَالَ قَدْرُ خَمْسِينَ آيَةً
