What is the ruling on repeating an act that is not part of prayer many times and without an excuse?

Repeating an act, which is not part of prayer, many times without an excuse, that is to say, performing amal kathir, invalidates prayer according to Hanafis. It is hard to draw a certain line for amal kathir. For some scholars, it means performing an act unrelated to prayer by means of two hands and for some others it means performing an act three times in a row. According to the other opinion preferred, it means performing an act which makes an onlooker think that the person is not in prayer. In this respect, if a behavior that is not similar to the acts in prayer and cannot be associated with prayer gives the impression that a person is not in prayer, it is included in amal kathir and invalidates prayer. The person who establishes prayer should evaluate his acts in the prayer and whether they invalidate prayer or not according to these explanations (Ibn Abidin, Radd al-Muhtar, II, 385, 406-407).
