The ruling on one who enters the state of ihram in Ramadan for 'Umrah, combining it with Hajj

Question: Your Eminence! This message came from Muhammad Masrur al-Huwayth and his family, Riyadh. There are also two other messages similar to this one; one from Shafi'ah Mutayr al-Ghazwani and one from Sultan Muhammad al-Sultan, Oman. They say: We arrived at the miqat with our family, and we all entered the state of ihram. I was the eldest among them and I knew them the rites of Hajj. I responded to the call, and they responded with my response. I forgot and said: "Labbaik Allahumma Labbaik..." and so on, "Labbaik 'Umrah combined with Hajj." We only wanted to perform 'Umrah in Ramadan. When we reached the Sacred House, some members of the family said: Why did you mention Hajj in the talbiyah when we do not want to perform Hajj? At that point, I remembered. Please inform us: Are we required to stay in Makkah until we perform Hajj, or are we required to offer a sacrificial animal and return to our families?

Answer:
In the name of Allah, the Most Gracious, the Most Merciful. Praise be to Allah, and may Allah send prayers and blessings upon the Messenger of Allah, and upon his family and his Companions, and upon those who follow his guidance. As for what follows:
This question, regarding the brothers mentioned entering the state of ihram from the miqat in Ramadan, with their talbiyah for 'Umrah combined with Hajj, does not require you, O questioner, to stay in Makkah until Hajj. Nor is a sacrificial animal required of you. Rather, 'Umrah in Ramadan is not described as combining it with Hajj.
Your saying in the talbiyah: "combined with Hajj," does not harm and does not affect anything. This is only for those who intend to stay and perform Hajj after Ramadan. As for one who does not intend that, he does not say it, but rather says: "Labbaik 'Umrah," even if he intended to stay until Hajj. It is not necessary for him to say: "combined with it for Hajj." The intention in his heart is sufficient. Then, if he did say that: "Labbaik 'Umrah combined with it for Hajj," and intended not to perform Hajj, he is not required to stay until Hajj. It is not necessary, for he may intend it and then something else occurs that prevents him from doing so, so there is no blame on him.
In any case: You, O brother, and those with you from the group who all responded with your talbiyah for 'Umrah combined with it for Hajj, that does not harm them, and there is no blame on them. They are not required to stay until they perform Hajj, and no expiation is required of them. Praise be to Allah.
