وحَدَّثَنِي حَرْمَلَةُ بْنُ يَحْيَى ، حَدَّثَنَا ابْنُ وَهْبٍ ، أَخْبَرَنِي عَمْرُو بْنُ الْحَارِثِ ، عَنِ ابْنِ شِهَابٍ ، عَنْ عُرْوَةَ بْنِ الزُّبَيْرِ ، عَنْ عَائِشَةَ زَوْجِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ، قَالَتْ : كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ، " يُصَلِّي فِيمَا بَيْنَ أَنْ يَفْرُغَ مِنْ صَلَاةِ الْعِشَاءِ ، وَهِيَ الَّتِي يَدْعُو النَّاسُ الْعَتَمَةَ إِلَى الْفَجْرِ إِحْدَى عَشْرَةَ رَكْعَةً ، يُسَلِّمُ بَيْنَ كُلِّ رَكْعَتَيْنِ وَيُوتِرُ بِوَاحِدَةٍ ، فَإِذَا سَكَتَ الْمُؤَذِّنُ مِنْ صَلَاةِ الْفَجْرِ ، وَتَبَيَّنَ لَهُ الْفَجْرُ وَجَاءَهُ الْمُؤَذِّنُ ، قَامَ فَرَكَعَ رَكْعَتَيْنِ خَفِيفَتَيْنِ ، ثُمَّ اضْطَجَعَ عَلَى شِقِّهِ الأَيْمَنِ ، حَتَّى يَأْتِيَهُ الْمُؤَذِّنُ لِلإِقَامَةِ " .
'A'isha, the wife of the Apostle of Allah (ﷺ) , said that between the time when the Messenger of Allah (ﷺ) finished the 'Isha' prayer which is called 'Atama by the people, he used to pray eleven rak'ahs, uttering the salutation at the end of every two rak'ahs, and observing the Witr with a single one. And when the Mu'adhdhin had finished the call (for the) dawn prayer and he saw the dawn clearly and the Mu'adhdhin had come to him, he stood up and prayed two short rak'ahs. Then he lay down on his right side till the Mu'adhdhin came to him for lqama.
