Accordingly, while casting the stones he faces the Kaʿbah, stones the jamarāt in their prescribed order, keeping them consecutive without separating or reversing them. He begins with the first jamrah, throwing at it seven pebbles—casting them, not placing them—and he must not hurl two or more pebbles at once; if he does, they count as only one. When he finishes the seven, he moves forward, stands before it for a good while, and invokes Allah with whatever supplications he can. He then stones the second, the middle jamrah, after which he moves off to the left, into the valley bed, and again prolongs his standing there in supplication. Next he stones the third, Jamrat al-ʿAqabah, with seven pebbles as well, casting from its lower side and without pausing there; were he to stone it from the upper side, it would still be valid. With every pebble he pronounces the takbīr, for the sunnah remembrance during the stoning is to say “Allāhu akbar,” not any other formula. During the Days of Minā he is to stone the jamarāt on foot, unlike the stoning on the Day of Sacrifice.
The pebbles must be clean, free from impurity, and not stones that have already been used; if he casts stones that have been used before, the rite is invalid. Ibn al-Qāsim, reporting from Mālik, said that if this occurs with only a single pebble it is nonetheless acceptable, and when the matter was put to Ibn al-Qāsim he delivered that ruling. Pebbles should not be taken from the gravel of the Sacred Mosque; scholars prefer that they be collected from Muzdalifah, and if that is not possible then from any clean spot. Hardened clay or anything other than stone is not acceptable. If one picks up his pebbles from a clean place he need not wash them, yet should he fail to wash impure stones or throw with stones already used, Mālik is reported to have said that he has acted badly, though the rite still counts.
Whoever reverses the order—stoning the last jamrah first, then the middle, then the first—must redo the middle and then the last; similarly, if he stones the middle and then the first, he must repeat the middle and then the last; and if he stones the middle, then the last, then the first, he must repeat the rite.
