Mufti saheb explain ammale katheer i was told that movement in a rukn for more then three tasbeehs, moving both hands and if somone sees you and believes your not in salaah what if somone itches his beard for more then 3 subhanaalah and hes got a itch what then please just make it easy for me from your understanding what is and what isnt amale katheer and in which cases namaaz is broken In the name of Allah, the most Beneficent, the most Merciful.
Amal katheer is that an onlooker who sees him in the act from a distance becomes certain that he is not in salah, otherwise it will be amal qaleel which does not break ones salah. Using both hands from its normal place is amal katheer whereas using one hand from its normal place in salah is considered as amal qaleel. This is the correct definition with regards to amal kathir. Thus it is not the number of times you make the movement that invalidates your salah, rather the type of movement.
Another definition of amal katheer is that if there are three successive actions in salah that will constitute amal katheer hence, break your salah.
The answer to your question is that as long as you ithced your beard with one hand then your salah will be intact. Out of precaution it is best you don’t itch your beard three times consecutively to keep away from the differences amonst the scholars regarding this issue.
