What is the ruling regarding someone who stood at Arafah during Hajj but did not perform the Sa'i or shave due to ignorance?

Sa'y between Safa and Marwa is one of the pillars of Hajj according to the majority of scholars. The second tahallul (exiting the state of ihram (definition)) is not achieved without it, along with the tawaf (definition). If the parents did not perform Sa'y after assuming ihram, whether performing Hajj mutamatti' (tamattu'), qarin (qiran (definition)), or mufrid (ifrad (definition)), they are still in their state of ihram. They must refrain from sexual intercourse and its preludes. They must go to Mecca to complete the Sa'y. It is safer to repeat the tawaf along with the Sa'y to ensure continuity. If they are unable to travel, they can exit the state of ihram by sacrificing a hady (sacrificial animal), or by fasting ten days if they are unable to provide the hady. As for sexual intercourse that occurred due to ignorance, there is no penalty for it. They must perform shaving or shortening of the hair, even if in their own country. If they intentionally committed prohibitions of ihram before shaving or shortening their hair, they are required to offer fidyah (definition) (expiation).
