عَائِشَة رضى الله عنها أَخْبَرَتْهُ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَانَ يُصَلِّي إِحْدَى عَشْرَةَ رَكْعَةً، كَانَتْ تِلْكَ صَلاَتَهُ، يَسْجُدُ السَّجْدَةَ مِنْ ذَلِكَ قَدْرَ مَا يَقْرَأُ أَحَدُكُمْ خَمْسِينَ آيَةً قَبْلَ أَنْ يَرْفَعَ رَأْسَهُ، وَيَرْكَعُ رَكْعَتَيْنِ قَبْلَ صَلاَةِ الْفَجْرِ، ثُمَّ يَضْطَجِعُ عَلَى شِقِّهِ الأَيْمَنِ حَتَّى يَأْتِيَهُ الْمُنَادِي لِلصَّلاَةِ.
Hazrat Aishara reported that, “Allah’s Messengersa of Allah used to offer eleven rak‘at; that was his prayer – meaning his night prayer. In that prayer, he would remain in prostration for so long that, before he raised his head, one of you would be able to recite fifty verses [of the Quran in that span of time]. He would also perform two rak‘at before the Fajr prayer, then lie down on his right side until the caller to prayer [muezzin] came to him.”
(Sahih Bukhari, Kitab al-witr, Bab ma ja’a fi l-witr, Hadith 994)
