Hadith 12129

(حديث مرفوع) حَدَّثَنَا يَحْيَى ، عَنْ حُمَيْدٍ ، قَالَ : سُئِلَ أَنَسٌ عَنْ صَلَاةِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بِاللَّيْلِ ؟ ، فَقَالَ : " مَا كُنَّا نَشَاءُ أَنْ نَرَاهُ مُصَلِّيًا إِلَّا رَأَيْنَاهُ ، وَلَا نَائِمًا إِلَّا رَأَيْنَاهُ " .
Humaid says that a person asked Hazrat Anas (may Allah be pleased with him) about the night prayer of the Prophet (peace and blessings be upon him), so he replied that whenever we wanted to see the Prophet (peace and blessings be upon him) praying at night, we could see him, and whenever we intended to see him sleeping, we could also see that.
