Staying overnight in Mina is among the obligatory acts of Hajj, and whoever leaves it for an excuse makes it up with a sacrificial animal

Question:
The first message in this episode is one that reached the program from the Noble City of the Prophet, sent by one of the female listeners from there. She says: Your sister, Umm Anas bint Sa'id, an Egyptian. Our sister says in her message that she has three questions. The first question says: By the grace of Allah the Exalted, my husband and I were among the pilgrims to the House of Allah, and by the grace of Allah we performed all the rituals completely. However, due to certain circumstances, we were compelled not to stay overnight in Mina. On the first day of the festival, we stoned the Pillar of Aqabah, then we left Mina, and then we returned in the evening. I was ill, and my Lord knows that I could not sit for more than half an hour or just an hour. So my husband was compelled to take me and return me to where we were staying in Makkah. Therefore, on the second day, at midnight, we would sit for a little while and then return to our lodging. I do not know if there is anything required of us in this, or if our Hajj is valid? And if there is a deficiency, what must we do to make our Hajj complete? May Allah reward you with good.

Answer:
In the name of Allah, the Most Gracious, the Most Merciful. Praise be to Allah, Lord of the worlds, and may Allah send prayers and blessings upon our Prophet Muhammad, and upon his family and all his Companions. As for what follows, staying overnight in Mina during the nights of the days of Tashriq is, for the pilgrim, an obligatory act of Hajj. It is not permissible to leave it except for a valid legal excuse. And whoever leaves it, his Hajj is valid, but the leaving of the overnight stay is made up with a sacrificial animal, a sacrificial animal for making up the deficiency.
As for what the questioner mentioned about her being ill, and that her husband was compelled to take her to the lodging, if the reality is as mentioned, and that she is unable to remain in Mina, and that she needs her husband to accompany her to care for her, then there is no overnight stay required of them in this case; because they are excused. But if they left the overnight stay without an excuse, then it is an obligatory act of Hajj that is made up with a sacrificial animal, which is slaughtering a sheep in Makkah that is acceptable for the 'Id sacrifice, and it is distributed to the poor of the Haram. And whoever is unable to slaughter the ransom payment, he fasts for ten days. The outcome is that this depends on your situation in leaving the overnight stay. If it was for the excuse of illness, and accompanying the sick person; then it is a valid legal excuse with which the overnight stay is dropped. But if it was for no excuse, and it was merely negligence; then this obligatory act that was left is made up with a sacrificial animal as we mentioned.
