Wa’il b.Hujr said:

He saw that when the Prophetﷺ stood up to pray he raised his hands till they were in front of his shoulders and placed his thumbs opposite his ears; then he uttered the Takbir (Allah is most great).

حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا يَزِيدُ، - يَعْنِي ابْنَ زُرَيْعٍ - حَدَّثَنَا الْمَسْعُودِيُّ، حَدَّثَنِي عَبْدُ الْجَبَّارِ بْنُ وَائِلٍ، حَدَّثَنِي أَهْلُ، بَيْتِي عَنْ أَبِي أَنَّهُ، حَدَّثَهُمْ أَنَّهُ، رَأَى رَسُولَ اللَّهِ ﷺ يَرْفَعُ يَدَيْهِ مَعَ التَّكْبِيرَةِ .
