Waail bin Hajar reported,

I prayed behind the Messenger of Allah ﷺ. He said the takbir when he began the prayer and raised his hands, and when he was about to bow he raised his hands, and when he lifted his head from the bowing he raised his hands. He placed his palms down, held his arms away from his sides, spread out his left thigh under his right, and pointed with his index finger.

حدثنا محمد بن جعفر حدثنا شعبة عن عاصم بن كليب عن أبيه

عن وائل الحضرمي قال

صليت خلف رسول الله ﷺ فكبر حين دخل ورفع يده وحين أراد أن يركع رفع يديه وحين رفع رأسه من الركوع رفع يديه ووضع كفيه وجافى وفرش فخذه اليسرى من اليمنى وأشار بإصبعه السبابة
