وَعَنْهُ: أَنَّهُ رَقَدَ عِنْدَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَاسْتَيْقَظَ فَتَسَوَّكَ وَتَوَضَّأَ وَهُوَ يَقُول: «(إِن فِي خلق السَّمَاوَات وَالْأَرْض...) حَتَّى خَتَمَ السُّورَةَ ثُمَّ قَامَ فَصَلَّى رَكْعَتَيْنِ أَطَالَ فِيهِمَا الْقِيَامَ وَالرُّكُوعَ وَالسُّجُودَ ثُمَّ انْصَرَفَ فَنَامَ حَتَّى نَفَخَ ثُمَّ فَعَلَ ذَلِكَ ثَلَاثَ مَرَّاتٍ سِتَّ رَكَعَاتٍ كُلُّ ذَلِكَ يَسْتَاكُ وَيَتَوَضَّأُ وَيَقْرَأُ هَؤُلَاءِ الْآيَاتِ ثُمَّ أَوْتَرَ بِثَلَاثٍ»
He said that once when he slept in the house of God’s Messenger, he awoke, cleaned his teeth and performed ablution, saying meanwhile, “In the creation of the heavens and the earth,” to the end of the sura. He then stood up and prayed two rakas, standing, bowing and prostrating himself at length in them. Then he finished, went to sleep and snored.
He did that three times, six rakas altogether, each time cleaning his teeth, performing ablution and reciting these verses. Then he performed a witr of three rakas.
