What is the meaning of staying overnight in Mina, and does it include dhikr, reciting the Quran, and performing Tahajjud, or are there specific rituals to be performed, and what is the guidance of the Prophet, peace and blessings be upon him, regarding this?

Staying overnight in Mina on the ninth night of Dhul-Hijjah is a Sunnah (definition) by consensus, and it is obligatory during the nights of the Days of Tashreeq. Its meaning is to remain in Mina for most of the night. No specific dhikr (remembrance) or particular prayer has been preserved from the Prophet, peace be upon him, for Mina, but he used to remember Allah in all his states. The Days of Tashreeq are days of remembrance of Allah, as indicated by the Quranic verses and prophetic traditions. Whoever stays in Mina for most of the night has fulfilled the obligation, and if he strives in recitation, dhikr, and reading the Quran, that is good.
