Sunan an-Nasai
أَخْبَرَنَا مُحَمَّدُ بْنُ يَحْيَى بْنِ أَيُّوبَ، قَالَ أَنْبَأَنَا وَكِيعٌ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ عَاصِمٍ، عَنْ زِرٍّ، قَالَ قُلْنَا لِحُذَيْفَةَ أَىَّ سَاعَةٍ تَسَحَّرْتَ مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم قَالَ هُوَ النَّهَارُ إِلاَّ أَنَّ الشَّمْسَ لَمْ تَطْلُعْ .
It was narrated that Zirr said: "We said to Hudhaifah: 'At what time did you take Sahur with the Messenger of Allah?' He said: 'It was daytime, but before the sun had risen." (Daif)
