[Machine] The Messenger of Allah ﷺ stood at Arafat, and when he said "Labbaik Allahumma labbaik", he said, "Verily, the best is the good of the Hereafter." Al-Bukhari narrated this with the chain of Ikrima, and Muslim narrated it with the chain of Dawud. This hadith is authentic and they both did not exclude it.
أَنَّ رَسُولَ اللَّهِ ﷺ وَقَفَ بِعَرَفَاتٍ فَلَمَّا قَالَ «لَبَّيْكَ اللَّهُمَّ لَبَّيْكَ» قَالَ «إِنَّمَا الْخَيْرُ خَيْرُ الْآخِرَةِ» قَدِ احْتَجَّ الْبُخَارِيُّ بِعِكْرِمَةَ وَاحْتَجَّ مُسْلِمٌ بِدَاوُدَ وَهَذَا الْحَدِيثُ صَحِيحٌ لَمْ يُخَرِّجَاهُ
