"When Messenger of Allah performed the Takbir for Salat he would spread his fingers."  

كَانَ رَسُولُ اللَّهِ ﷺ إِذَا كَبَّرَ لِلصَّلاَةِ نَشَرَ أَصَابِعَهُ  

"When Messenger of Allah would enter the Salat he would raise his hands while they were extended."  

سَمِعْتُ أَبَا هُرَيْرَةَ يَقُولُ كَانَ رَسُولُ اللَّهِ ﷺ إِذَا قَامَ إِلَى الصَّلاَةِ رَفَعَ يَدَيْهِ مَدًّا
