Sunan Ibn Majah Book 5, Hadith 882

حَدَّثَنَا الْحَسَنُ بْنُ عَلِيٍّ الْخَلاَّلُ، حَدَّثَنَا يَزِيدُ بْنُ هَارُونَ، أَنْبَأَنَا شَرِيكٌ، عَنْ عَاصِمِ بْنِ كُلَيْبٍ، عَنْ أَبِيهِ، عَنْ وَائِلِ بْنِ حُجْرٍ، قَالَ رَأَيْتُ النَّبِيَّ ـ صلى الله عليه وسلم ـ إِذَا سَجَدَ وَضَعَ رُكْبَتَيْهِ قَبْلَ يَدَيْهِ وَإِذَا قَامَ مِنَ السُّجُودِ رَفَعَ يَدَيْهِ قَبْلَ رُكْبَتَيْهِ ‏.‏

It was narrated that Wa’il bin Hujr said:“I saw the Prophet (ﷺ) when he prostrated and put his knees on the ground before his hands, and when he stood up after prostrating, he took his hands off the ground before his knees.”
