Narrated Aiyub:
حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ ، قَالَ حَدَّثَنَا وُهَيْبٌ ، قَالَ حَدَّثَنَا أَيُّوبُ ، عَنْ أَبِي قِلاَبَةَ ، قَالَ جَاءَنَا مَالِكُ بْنُ الْحُوَيْرِثِ فِي مَسْجِدِنَا هَذَا فَقَالَ إِنِّي لأُصَلِّي بِكُمْ، وَمَا أُرِيدُ الصَّلاَةَ، أُصَلِّي كَيْفَ رَأَيْتُ النَّبِيَّ صلى الله عليه وسلم يُصَلِّي. فَقُلْتُ لأَبِي قِلاَبَةَ كَيْفَ كَانَ يُصَلِّي قَالَ مِثْلَ شَيْخِنَا هَذَا. قَالَ وَكَانَ شَيْخًا يَجْلِسُ إِذَا رَفَعَ رَأْسَهُ مِنَ السُّجُودِ قَبْلَ أَنْ يَنْهَضَ فِي الرَّكْعَةِ الأُولَى.
Abu Qilaba said, "Malik bin Huwairith came to this Mosque of ours and said, 'I pray in front of you and my aim is not to lead the prayer but to show you the way in which the Prophet (ﷺ) used to pray.' " I asked Abu Qilaba, "How did he use to pray?' " He replied, "(The Prophet (ﷺ) used to pray) like this Sheikh of ours and the Sheikh used to sit for a while after the prostration, before getting up after the first rak`a. "
