Hadith on Arafat: Allah frees His servants from Hellfire on the day of Arafat during the Hajj pilgrimage

Aisha reported: The Messenger of Allah, peace be upon him, said, “There is no day upon which Allah frees His servants from the Hellfire more than the day of Arafat; He draws near and then He praises them to the angels, saying: what do these want?”
[Sahih Muslim, Book 7, Number 3126]

قَالَتْ عَائِشَةُ إِنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ مَا مِنْ يَوْمٍ أَكْثَرَ مِنْ أَنْ يُعْتِقَ اللَّهُ فِيهِ عَبْدًا مِنْ النَّارِ مِنْ يَوْمِ عَرَفَةَ وَإِنَّهُ لَيَدْنُو ثُمَّ يُبَاهِي بِهِمْ الْمَلَائِكَةَ فَيَقُولُ مَا أَرَادَ هَؤُلَاءِ
