The Book of Hajj
The Obligation of Hajj (Pilgrimage) and its Excellence
وَعَنْهَا أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ، قَالَ: مَا مِنْ يَوْمٍ أَكْثَرَ مِنْ أَنْ يُعْتِقَ اللَّهُ فِيهِ عَبْدًا مِنَ النَّارِ مِنْ يَوْمِ عَرَفَةَ ((رَوَاهُ مُسْلِم)).
'Aishah (May Allah be pleased with her) reported: The Messenger of Allah (ﷺ) said, "There is no day on which Allah sets free more slaves from Hell than He does on the Day of 'Arafah." [Muslim].
