Spending the night in Mina on the eighth night of Dhul-Hijjah

Q 2: I performed Hajj through a local company and we stayed outside Mina. I spent the night there on the eve of the 9th of Dhul-Hijjah but spent the nights of the Days of Tashriq (11th, 12th and 13th of Dhul-Hijjah) at Mina. Is spending the eve of the 9th of Dhul-Hijjah Wajib (obligatory) or a Sunnah (supererogatory act of worship following the example of the Prophet)? If it is Wajib, what must I do? May Allah reward you with the best!

A 2: Staying the night at Mina on the eve of the ninth of Dhul-Hijjah is a Sunnah and not Wajib. Therefore, there is nothing on you for neglecting to spend that night at Mina. However, you missed the reward for the Sunnah of spending the night there.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
