Sunan Abi Dawud, 742
sahih· Al-Albani

Nafi’ said:

When ‘Abd Allah b. ‘Umar began his prayer, he raised his hands opposite to his shoulders; and when he raised his head after bowing, he raised them lower than that. Abu Dawud said: So as far as I know, no one narrated the words “he raised them lower that that” except Malik.

حَدَّثَنَا الْقَعْنَبِيُّ، عَنْ مَالِكٍ، عَنْ نَافِعٍ، أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ، كَانَ إِذَا ابْتَدَأَ الصَّلاَةَ يَرْفَعُ يَدَيْهِ حَذْوَ مَنْكِبَيْهِ وَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ رَفَعَهُمَا دُونَ ذَلِكَ ‏.‏ قَالَ أَبُو دَاوُدَ لَمْ يَذْكُرْ رَفْعَهُمَا دُونَ ذَلِكَ ‏.‏ أَحَدٌ غَيْرَ مَالِكٍ فِيمَا أَعْلَمُ ‏.‏
