5. Ali ibn Ibrahim has narrated from his father from and Muhammad ibn ‘Isma‘il has narrated from al-Fadl ibn Shadhan from Safwan from Mu‘awiyah ibn ‘Ammar who has said the following: “About a man who had twenty one pebbles and threw them but one remained extra and he did not know which of the three had one less. He (the Imam) said, ‘He must return and throw one pebble on each one. If a pebble falls from the hand of a man, he can take one from under his feet and throw it.’ He (the Imam) said, ‘If you throw a pebble and it hits the carriage you must repeat throwing one in its place, but if it hits a man or a camel then hits al-Jamar it is sufficient.’ He (the Imam) said, ‘About a man who throws four on al-’Ula’ and seven on each of the other two, he must go back to throw three more on al-’Ula’. In so doing his task is complete; but if he has thrown three on al-’Ula’ and seven on each of the other two, he must repeat and throw pebbles on all of them, seven pebbles on each one. If he throws three pebbles on al-Wusta’ then he throws on al-’Ukhra’, he must throw on al-Wusta’ seven pebbles. If he has thrown four on al-Wusta he must go back to throw three more.’ I then asked him (the Imam) about a man who reverses the order so he begins with al-’Aqabah then al-Wusta’ then al-’Uzma’. He (the Imam) said, ‘He must repeat throwing on al-Wusta’ then al-‘Aqabah even if it is done the next day.’”
