Hadith 5983
Jabir b. Samura told that he heard God's messenger say, "Islam will continue to be strong during the time of twelve Caliphs all of whom belong to Quraish." A version has "Men's interests will continue to proceed well as long as they are governed by twelve men all of whom belong to Quraish." Another version has, "The religion will continue to be established till the last hour comes, and there are twelve Caliphs over them, all of whom belong to Quraish." (Bukhari and Muslim.)
وَعَنْ جَابِرِ بْنِ سَمُرَةَ قَالَ: سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: «لَا يَزَالُ الْإِسْلَامُ عَزِيزًا إِلَى اثْنَيْ عَشَرَ خَلِيفَةً كُلُّهُمْ مِنْ قُرَيْشٍ» . وَفِي رِوَايَةٍ: «لَا يَزَالُ أَمْرُ النَّاسِ مَاضِيًا مَا وَلِيَهُمُ اثْنَا عَشَرَ رَجُلًا كُلُّهُمْ مِنْ قُرَيْشٍ» . وَفِي رِوَايَةٍ: «لَا يَزَالُ الدِّينُ قَائِمًا حَتَّى تَقُومَ السَّاعَة أَو يَكُونُ عَلَيْهِمُ اثْنَا عَشَرَ خَلِيفَةً كُلُّهُمْ مِنْ قُرَيْش» . مُتَّفق عَلَيْهِ
