Dear Brother / Sister,

The following rules are given in the books of Furu' for amal kathir (major action) and amal qalil (insignificant action):

1) Amal Kathir is the action of the praying person that makes the onlooker think surely that he/she is not praying; and the action that causes the onlooker doubt whether he is praying or not is amal qalil.

2) The habitual action which is done with two hands is amal kathir. The decree does not change when this is done with one hand: Such as wrapping turban cloth over skullcap and belting. The habitual action which is performed with one hand is amal qalil; such as wearing and removing the skullcap. However, if this repeated thrice, then it will be amal kathir.

3) The successive actions which are done three times is amal kathir; if not it is amal qalil.

4) Amal kathir is the action which is done deliberately.

5) The situation is left to the opinion of the person who is praying. What he considers to be much is amal kathir and what he considers to be little is amal qalil. (Ibn Abidin Trans., Istanbul 1982, II, 537,538)
