Malik b. Huwairith reported:The Messenger of Allah (ﷺ) raised his hands apposite his ears at the time of reciting the takbir (i. e. at the time of beginning the prayer) and then again raised his hands apposite the ears at the time of bowing and when he lifted his head after bowing he said: Allah listened to him who praised Him, and did like it (raised his hands up to the ears).
حَدَّثَنِي أَبُو كَامِلٍ الْجَحْدَرِيُّ، حَدَّثَنَا أَبُو عَوَانَةَ، عَنْ قَتَادَةَ، عَنْ نَصْرِ بْنِ عَاصِمٍ، عَنْ مَالِكِ بْنِ الْحُوَيْرِثِ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَانَ إِذَا كَبَّرَ رَفَعَ يَدَيْهِ حَتَّى يُحَاذِيَ بِهِمَا أُذُنَيْهِ وَإِذَا رَكَعَ رَفَعَ يَدَيْهِ حَتَّى يُحَاذِيَ بِهِمَا أُذُنَيْهِ وَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ فَقَالَ " سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ " . فَعَلَ مِثْلَ ذَلِكَ .
