Sahih Muslim Book - 4, Hadith - 864

حَدَّثَنَا يَحْيَى بْنُ يَحْيَى أَخْبَرَنَا خَالِدُ بْنُ عَبْدِ اللَّهِ عَنْ خَالِدٍ عَنْ أَبِي قِلَابَةَ أَنَّهُ رَأَى مَالِكَ بْنَ الْحُوَيْرِثِ إِذَا صَلَّى كَبَّرَ ثُمَّ رَفَعَ يَدَيْهِ وَإِذَا أَرَادَ أَنْ يَرْكَعَ رَفَعَ يَدَيْهِ وَإِذَا رَفَعَ رَأْسَهُ مِنْ الرُّكُوعِ رَفَعَ يَدَيْهِ وَحَدَّثَ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَانَ يَفْعَلُ هَكَذَا.

It was narrated from Abu Qilabah that he saw Malik bin Al-Huwairith, when he prayed, saying the Takbir then raising his hands. When he wanted to bow, he raised his hands, and when he raised his head from bowing he raised his hands. And he narrated that the Messenger of Allah (s.a.w) used to do that.
