The Messenger of Allah (ﷺ) said: "You will compete with one another, then you will envy one another, then you will turn your backs on one another, then you will hate one another, then you will go to the poor (in character) among the Muhajirun and appoint some of them as leaders of others.”

It was narrated from ‘Abdullah bin ‘Amr bin ‘As that the Messenger of Allah (ﷺ) said:

“When the treasures of Persia and Rome are opened for you, what kind of people will you be?” ‘Abdur-Rahman bin ‘Awf said: “We will say what Allah has commanded us to say.” The Messenger of Allah (ﷺ) said: “Or something other than that. You will compete with one another (for the pleasures of this world), then you will envy one another, then you will turn your backs on one another, then you will hate one another, or something like that. Then you will go to the poor (in character) among the Muhajirun and appoint some of them as leaders of others.”

حَدَّثَنَا عَمْرُو بْنُ سَوَّادٍ الْمِصْرِيُّ، أَخْبَرَنِي عَبْدُ اللَّهِ بْنُ وَهْبٍ، أَنْبَأَنَا عَمْرُو بْنُ الْحَارِثِ، أَنَّ بَكْرَ بْنَ سَوَادَةَ، حَدَّثَهُ أَنَّ يَزِيدَ بْنَ رَبَاحٍ حَدَّثَهُ عَنْ عَبْدِ اللَّهِ بْنِ عَمْرِو بْنِ الْعَاصِ، عَنْ رَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ أَنَّهُ قَالَ ‏"‏ إِذَا فُتِحَتْ عَلَيْكُمْ خَزَائِنُ فَارِسَ وَالرُّومِ أَىُّ قَوْمٍ أَنْتُمْ ‏"‏ ‏.‏ قَالَ عَبْدُ الرَّحْمَنِ بْنُ عَوْفٍ نَقُولُ كَمَا أَمَرَنَا اللَّهُ ‏.‏ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ ‏"‏ أَوْ غَيْرَ ذَلِكَ تَتَنَافَسُونَ ثُمَّ تَتَحَاسَدُونَ ثُمَّ تَتَدَابَرُونَ ثُمَّ تَتَبَاغَضُونَ أَوْ نَحْوَ ذَلِكَ ثُمَّ تَنْطَلِقُونَ فِي مَسَاكِينِ الْمُهَاجِرِينَ فَتَجْعَلُونَ بَعْضَهُمْ عَلَى رِقَابِ بَعْضٍ ‏"‏ ‏.‏

Rasulullah (ﷺ): Do not go astray after me by cutting the necks of each other. Convey this message to those who are absent, for some of those to whom it is conveyed may comprehend it better [than those present]

Sahih al-Bukhari 5550
Narrated Abu Bakra:

The Prophet (ﷺ) said, "Time has come back to its original state which it had on the day Allah created the Heavens and the Earth. The year is twelve months, four of which are sacred, three of them are in succession, namely Dhul-Qa'da, Dhul Hijja and Muharram, (the fourth being) Rajab Mudar which is between Juma'da (ath-thamj and Sha'ban. The Prophet (ﷺ) then asked, "Which month is this?" We said, "Allah and his Apostle know better." He kept silent so long that we thought that he would call it by a name other than its real name. He said, "Isn't it the month of Dhul-Hijja?" We said, "Yes." He said, "Which town is this?" We said, "Allah and His Apostle know better." He kept silent so long that we thought that he would call it t,y a name other than its real name. He said, "isn't it the town (of Mecca)?" We replied, "Yes." He said, "What day is today?" We replied, "Allah and His Apostle know better." He kept silent so long that we thought that he would call it by a name other than its real name. He said, "Isn't it the day of Nahr?" We replied, "Yes." He then said, "Your blood, properties and honor are as sacred to one another as this day of yours in this town of yours in this month of yours. You will meet your Lord, and He will ask you about your deeds. Beware! Do not go astray after me by cutting the necks of each other. It is incumbent upon those who are present to convey this message to those who are absent, for some of those to whom it is conveyed may comprehend it better than some of those who have heard it directly." (Muhammad, the sub-narrator, on mentioning this used to say: The Prophet then said, "No doubt! Haven't I delivered (Allah's) Message (to you)? Haven't I delivered Allah's message (to you)?"
