Rule 337...
Rule 337: It is permitted to sit at Safaa or Marwah or between them to rest but, as a matter of caution, one must avoid sitting between Safaa and Marwah, except for those who are tired, or to pray at the earliest time. In these cases. one may complete the saee from where it had been interrupted. As a matter of caution, if one interrupts a saee one should complete it and then repeat it.
THE RULES OF SAEE Saee is one of the fundamentals of Hajj and if one omits to perform it deliberately, whether knowing the rule or ignorant of it or because the time became so short that it could not be performed before the period for stay at Arafaat, the Hajj is invalidated and he is subject to the rules applicable to one who deliberately omitted the tawaaf already mentioned above.
Rule 338: If one forgets to perform saee, one must perform it when one remembers but if one remembers after completion of the ceremonies of Hajj and is unable to perform the saee personally because of some restraint or difficulty, he is obliged to appoint an agent and in both such cases, the pilgrimage will be valid.
Rule 339: If a pilgrim is unable to perform the saee personally even by being carried on the shoulders of another man or on a wheelchair, he may appoint an agent to perform the saee on his behalf and his Hajj will be valid. Rule 340: As a matter of caution, a pilgrim must not delay the performance of saee after the tawaaf and prayers beyond the period necessary to avoid heat and exhaustion although it is permissible to delay it till night.
In ordinary circumstances it is not permissible to delay it to the next day. Rule 341: The rule on additions in saee is exactly the same as the rule in tawaaf. It invalidates the saee if additions are made knowingly and deliberately. However, if the addition is made out of ignorance of the rule, it is clear that the saee will not be invalidated but, as a matter of caution, must be repeated.
Rule 342: If a pilgrim makes addition in saee by mistake, the saee is valid but if the addition is a complete round or more, it is recommended that he should complete seven rounds to make a full saee apart from the first one. In this way he will complete at Safaa.
Rule 343: If a pilgrim deliberately makes less than the required rounds in saee, whether knowing the rule or not, and is unable to remedy it because of the required period of stay in Arafaat, his Hajj is invalidated and he is obliged to perform it again in the following year.
