Hadith: There is no day on which Allah sets free more of His slaves from Fire than the Day of ‘Arafah. He verily draws near, then He boasts about them before the angels saying: What do these people want?

عن عائشة رضي الله عنها مرفوعاً: «ما مِن يومٍ أكثر مِن أنْ يُعْتِقَ اللهُ فيه عبدًا مِن النارِ، مِن يومِ عرفة، وإنَّه ليدنو، ثم يُباهي بهم الملائكةَ، فيقول: ما أراد هؤلاء؟».
[صحيح] - [رواه مسلم]

‘Ā'ishah (may Allah be pleased with her) reported that the Prophet (may Allah's peace and blessings be upon him) said: "There is no day on which Allah sets free more of His slaves from Fire than the Day of ‘Arafah. He verily draws near, then He boasts about them before the angels saying: What do these people want?"
[Authentic hadith] - [Narrated by Muslim]

Explanation

There is no day on which Allah sets free more of His slaves from Fire than the Day of ‘Arafah. In other words, Allah, the Almighty, releases and saves from Fire whomever He wills on this day more than any other day. Allah, the Almighty, truly gets close to His slaves and boasts about them before the angels, showing the angels the virtue and honor of the pilgrims. Ahl As-Sunnah Wa al-Jamā‘ah believe that Allah, Glorified and Exalted, is truly Near to His slaves in a way that befits His majesty and grandeur. Allah is above His Throne and separate from His creation, and He truly gets close to them. "Allah asks the angels what these people want, and why they have left their families and homelands, spent their wealth, and exhausted their bodies. That is to say, they only seek forgiveness, the pleasure of Allah, His closeness, and visiting His House, and whatever they seek they will surely receive. The amount of what they receive is determined according to their intentions.
