Raising of the hands (rafʿ al-yadayn رفع اليدين) only once at the beginning of the Ṣalāh

ʿAbdullāh b. Masʿūd said: "Shall I not demonstrate the Ṣalāh of Messenger ﷺ of Allah to you?" Then he offered the Ṣalāh and he did not raise his hands except while saying the first takbīr."  

قَالَ عَبْدُ اللَّهِ بْنُ مَسْعُودٍ أَلاَ أُصَلِّي بِكُمْ صَلاَةَ رَسُولِ اللَّهِ ﷺ؟ فَصَلَّى، فَلَمْ يَرْفَعْ يَدَيْهِ إِلاَّ فِي أَوَّلِ مَرَّةٍ۔
