How the worshipper counts the rak'ahs

Question : But how does he count the rak'ahs?

Answer : Counting with the fingers is problematic, because when he bows, he must place his hands on his knees with his fingers spread apart. And when he prostrates, his hands must be spread out on the ground. He uses, for example, four dates pits in his pocket. Do you know what a date pit is? Do you know? What is a date pit? No, it is from the date, yes, the pit of the date palm. Yes, the one in the date. He puts four pits in his pocket, and when he prays the first rak'ah, he throws one out, and so on until they are all gone. This is permissible, because this is a need, and people often need it due to forgetfulness. They need it, so there is no harm in it.
