Assuming Ihram from the Miqat of Madinah

Q: I performed Hajj (pilgrimage) and made Ihram (ritual state for Hajj or 'Umrah) from the Miqat (site for entering the ritual state for Hajj or 'Umrah), and my intention was to perform Ifrad Hajj (performing Hajj only). Then I went to Makkah with my husband and after that we went to Al-Madinah on the fourth day of Dhul-Hijjah wearing the same clothes. We stayed in Madinah until the seventh of Dhul-Hijjah, and while we were passing by the Miqat of Dhul-Hulayfah, we made Tahallul (removal of the ritual state of Hajj or 'Umrah) and we made Ihram again with the same intention of Ifrad. In Makkah we made Tawaf (circumambulation of the Ka'bah) and Sa'y (going between Safa and Marwa during Hajj or 'Umrah) again. Are we required to do anything because of that, or is our Hajj valid? Yet, kindly be informed that the Miqat from which we made Ihram in the beginning was Yalamlam. A: If no sexual intercourse happened between you and your husband during your Tahallul, then you are not required to do anything, and what you have done when you repeated the Ihram was a mistake regarding which you are excused due to your ignorance of the ruling. But if you had sexual intercourse with your husband, then your Hajj is invalid, and you need to make it up next year. Moreover, you have to offer Fidyah (ransom), which is slaughtering a camel in Makkah and to distribute its meat to the poor of Makkah. By the same token, if your husband made the intention for Ifrad Hajj like you, then he needs to do exactly what you are supposed to do: making up for Hajj and offering Fidyah.
