Sahih al-Bukhari 3649
Narrated Abu Sa`id Al-Khudri:
"Allah's Messenger (ﷺ) said, "A time will come upon the people, when a group of people will wage a holy 
war and it will be said, 'Is there amongst you anyone who has accompanied Allah's Messenger (ﷺ)?' They 
will say, 'Yes.' And so victory will be bestowed on them. Then a time will come upon the people when 
a group of people will wage a holy war, and it will be said, "Is there amongst you anynone who has 
accompanied the companions of Allah's Messenger (ﷺ)?' They will say, 'Yes.' And so victory will be 
bestowed on them. Then a time will come upon the people when a group of people will wage a holy 
war, and it will be said, "Is there amongst you anyone who has been in the company of the 
companions of the companions of Allah's Messenger (ﷺ) ?' They will say, 'Yes.' And victory will be 
bestowed on them."
حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا سُفْيَانُ، عَنْ عَمْرٍو، قَالَ سَمِعْتُ جَابِرَ بْنَ عَبْدِ اللَّهِ ـ رضى الله عنهما ـ يَقُولُ حَدَّثَنَا أَبُو سَعِيدٍ الْخُدْرِيُّ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏
