None will be granted salvation more than those on the Day of ʿArafah

that the Messenger of Allah ﷺ said, "There is no day when Allah grants salvation to more servants from the Hellfire than the Day of ʿArafah. He draws near, then boasts about them to the angels, saying: 'What do these people desire (and He may grant them)?'"  

إِنَّ رَسُولَ اللَّهِ ﷺ قَالَ: «مَا مِنْ يَوْمٍ أَكْثَرَ مِنْ أَنْ يُعْتِقَ اللَّهُ فِيهِ عَبْدًا مِنَ النَّارِ مِنْ يَوْمِ عَرَفَةَ، وَإِنَّهُ لَيَدْنُو ثُمَّ يُبَاهِي بِهِمُ الْمَلاَئِكَةَ فَيَقُولُ: (مَا أَرَادَ هَؤُلاَءِ؟)»  

An Umra is an expiation for the sins committed between it and the next, and Hajj which is accepted will receive no other reward than Paradise.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ الْعُمْرَةُ إِلَى الْعُمْرَةِ كَفَّارَةٌ لِمَا بَيْنَهُمَا وَالْحَجُّ الْمَبْرُورُ لَيْسَ لَهُ جَزَاءٌ إِلاَّ الْجَنَّةُ  

This hadith has been narrated on the authority of Abu Huraira (Allah be pleased with him) through another chain of transmitters.  

عَنِ النَّبِيِّ ﷺ بِمِثْلِ حَدِيثِ مَالِكٍ  

He who came to this House (Ka'ba) (with the intention of performing Pilgrimage), and neither spoke indecently nor did he act wickedly. would return (free from sin) as on the (very first day) his mother bore him.  

قَالَ رَسُولُ اللَّهِ ﷺ مَنْ أَتَى هَذَا الْبَيْتَ فَلَمْ يَرْفُثْ وَلَمْ يَفْسُقْ رَجَعَ كَمَا وَلَدَتْهُ أُمُّهُ  

" He who performed Pilgrimage but neither spoke indecently nor acted wickedly."  

بِهَذَا الإِسْنَادِ وَفِي حَدِيثِهِمْ جَمِيعًا مَنْ حَجَّ فَلَمْ يَرْفُثْ وَلَمْ يَفْسُقْ  

A hadith like this has been narrated on the authority of Abu Huraira (Allah be pleased with him).  

عَنِ النَّبِيِّ ﷺ مِثْلَهُ
