The World Federation One Stop Fiqh

Ritual 431

It is obligatory to start rami of the First Jamrah , then the Middle and finally the Last. If this order is not followed, even due to an oversight or ignorance of the rule, the procedure must be repeated to achieve the proper sequence.

However, if one forgets or misses a Jamrah and throws four stones at the subsequent one before realising, he may complete the seven; there is no need to repeat the rami of the subsequent one.
