´It was narrated that Ziyad bin Subaih said:` "I prayed beside Ibn Umar and put my hand on my waist, and he did this to me-knocked it with his hand. When I had finished praying I said to a man: 'Who is this?' He said: "Abdullah bin Umar.' I said: 'O Abu Abdur-Rahman, why are you angry with me?' He said: 'This is the posture of crucifixion, and the Mesenger of Allah (ﷺ) forbade us to do this.'"

Hafiz Muhammad Ameen
892. Commentary:
➊ The person who places his hands on his waist (hips) has his elbows sticking out, and the hands of a person hanging on a cross are also extended outward; therefore, the position from the shoulders to the elbows is the same in both cases, and this is an objectionable posture. Moreover, the cross is a religious symbol of the Christians. Imitation in religious symbols is absolutely impermissible.
➋ From this blessed hadith, it is also understood that if any act contrary to the Sunnah is being done in prayer, it should be corrected; this does not invalidate the prayer.

903. Commentary:
➊ Placing the hands on the hips (or sides) during prayer is impermissible. Several reasons have been mentioned for this: one is the resemblance mentioned here, that those who were crucified were made to stand on the wood in this manner, with their hands away from their sides. Other opinions are that it resembles the posture of Satan, or it resembles the Jews, or it will be the posture of comfort for the inhabitants of Hell, or the arrogant stand in this way, or people stand like this in grief and sorrow, etc. [عون المعبود] In short, whatever the reason may be, this act is prohibited.
➋ The explanation of «اقعاءعلي القدمين» is as follows: «اقاء» refers to sitting on the heels, and it is occasionally permissible to sit in this manner between the two prostrations. For details, see the benefits of Sunan Abu Dawood, hadith [845].
