Sunan an-Nasa'i, Book 12, Hadith 61 (In-Book)

It was narrated that Wa'il bin Hujr said: "I saw the Messenger of Allah when he prostrated, he lowered his knees before his hands, and when he came up he raised his hands before his knees."

أَخْبَرَنَا الْحُسَيْنُ بْنُ عِيسَى الْقُومَسِيُّ الْبَسْطَامِيُّ، قَالَ حَدَّثَنَا يَزِيدُ، - وَهُوَ ابْنُ هَارُونَ - قَالَ أَنْبَأَنَا شَرِيكٌ، عَنْ عَاصِمِ بْنِ كُلَيْبٍ، عَنْ أَبِيهِ، عَنْ وَائِلِ بْنِ حُجْرٍ، قَالَ رَأَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم إِذَا سَجَدَ وَضَعَ رُكْبَتَيْهِ قَبْلَ يَدَيْهِ وَإِذَا نَهَضَ رَفَعَ يَدَيْهِ قَبْلَ رُكْبَتَيْهِ ‏.‏
