حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، وَبِشْرُ بْنُ مُعَاذٍ، قَالا‏:‏ حَدَّثَنَا أَبُو عَوَانَةَ، عَنْ زِيَادِ بْنِ عِلاقَةَ، عَنِ الْمُغِيرَةِ بْنِ شُعْبَةَ، قَالَ‏:‏ صَلَّى رَسُولُ اللهِ صلى الله عليه وسلم، حَتَّى انْتَفَخَتْ قَدَمَاهُ، فَقِيلَ لَهُ‏:‏ أَتَتَكَلَّفُ هَذَا، وَقَدْ غَفَرَ اللَّهُ لَكَ مَا تَقَدَّمَ مِنْ ذَنْبِكَ وَمَا تَأَخَّرَ‏؟‏ قَالَ‏:‏ أَفَلا أَكُونُ عَبْدًا شَكُورًا‏.‏

'A’isha said (may Allah be well pleased with her)

“Allah’s Messenger (Allah bless him and give him peace) used to perform eleven cycles of ritual prayer during the night, making one of them odd-numbered [witr], and when he had finished, he would recline on his right side.”
