"I heard An-Nu'man bin Bashir on the minbar in Hims saying: "We prayed Qiyam with the Messenger of Allah ﷺ during Ramadan on the night of the twenty-third until one-third of the night had passed, then we prayed Qiyam with him on the night of the twenty-fifth until one-half of the night had passed, then we prayed Qiyam with him on the night of the twenty-seventh until we thought that we would miss Al-Falah- that is what they used to call suhur." (Using translation from Nasāʾī 1606)
سَمِعْتُ النُّعْمَانَ بْنَ بَشِيرٍ عَلَى مِنْبَرِ حِمْصٍ يَقُولُ «قُمْنَا مَعَ رَسُولِ اللهِ ﷺ فِي شَهْرِ رَمَضَانَ لَيْلَةَ ثَلَاثٍ وَعِشْرِينَ إِلَى ثُلُثِ اللَّيْلِ الْأَوَّلِ ثُمَّ قُمْنَا مَعَهُ لَيْلَةَ خَمْسٍ وَعِشْرِينَ إِلَى نِصْفِ اللَّيْلِ ثُمَّ قُمْنَا معه لَيْلَةَ ِسبْعٍ وَعِشْرِينَ حَتَّى ظَنَنَّا أَنْ لَا نُدْرِكَ الْفَلَاحَ وَكَانُوا يُسَمُّونَهُ السَّحُورَ»
