Narrator:Zayd ibn Thābit
حَدَّثَنَا مُسْلِمُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا هِشَامٌ، حَدَّثَنَا قَتَادَةُ، عَنْ أَنَسٍ، عَنْ زَيْدِ بْنِ ثَابِتٍ ـ رضى الله عنه ـ قَالَ تَسَحَّرْنَا مَعَ النَّبِيِّ صلى الله عليه وسلم ثُمَّ قَامَ إِلَى الصَّلاَةِ. قُلْتُ
كَمْ كَانَ بَيْنَ الأَذَانِ وَالسَّحُورِ قَالَ قَدْرُ خَمْسِينَ آيَةً.
Zayd ibn Thābit (may Allah be pleased with him) reported:
We had Suhūr (pre-dawn meal) with the Prophet (may Allah's peace and blessings be upon him), and then he stood for prayer. I said: How long was the time between Adhān and Suhūr? He said: The time it takes to recite fifty verses.
