Ritual 378

Two things are to be taken into consideration regarding the stones:

1. They must have been picked within the boundaries of the Haram but not from the Holy Mosque or the Mosque of Khief, and better still, they be picked in Muzdalifah.

2. As a matter of precaution, they must not have been used for this purpose before; it is recommended (mustahab) that they be coloured, dotted and soft and of a thickness of a finger. When stoning, should be standing on one’s feet, and in a state of taharah.
