Ash-Shama'il Al-Muhammadiyah 279
'Abdullah ibn Shaqiq said:
“I asked 'A’isha (may Allah be well pleased with her) about the voluntary ritual prayers of Allah’s Messenger (Allah bless him and give him peace), and she said: ‘He used to spend a long night performing the ritual prayer while standing, and a long night while sitting, so if he recited the Qur’an while standing, he would bow and prostrate from a standing position, and if he recited while sitting, he would bow and prostrate from a sitting position.”
حَدَّثَنَا أَحْمَدُ بْنُ مَنِيعٍ، قَالَ‏:‏ حَدَّثَنَا هُشَيْمٌ، قَالَ‏:‏ حَدَّثَنَا خَالِدٌ الْحَذَّاءُ، عَنْ عَبْدِ اللهِ بْنِ شَقِيقٍ، قَالَ‏:‏ سَأَلْتُ عَائِشَةَ، عَنْ صَلاةِ رَسُولِ اللهِ صلى الله عليه وسلم، عَنْ تَطَوُّعِهِ، فَقَالَتْ‏:‏ كَانَ يُصَلِّي لَيْلا طَوِيلا قَائِمًا، وَلَيْلا طَوِيلا قَاعِدًا، فَإِذَا قَرَأَ وَهُوَ قَائِمٌ رَكَعَ وَسَجَدَ وَهُوَ قَائِمٌ، وَإِذَا قَرَأَ وَهُوَ جَالِسٌ رَكَعَ وَسَجَدَ وَهُوَ جَالِسٌ‏.‏
