حَدَّثَنَا هَنَّادُ بْنُ السَّرِيِّ، حَدَّثَنَا أَبُو الأَحْوَصِ، عَنْ أَبِي إِسْحَاقَ، عَنْ عَمْرِو بْنِ مَيْمُونٍ، عَنْ عَبْدِ اللَّهِ، قَالَ قَالَ لَنَا رَسُولُ اللَّهِ صلى الله عليه وسلم " أَمَا تَرْضَوْنَ أَنْ تَكُونُوا رُبُعَ أَهْلِ الْجَنَّةِ " قَالَ فَكَبَّرْنَا . ثُمَّ قَالَ " أَمَا تَرْضَوْنَ أَنْ تَكُونُوا ثُلُثَ أَهْلِ الْجَنَّةِ " قَالَ فَكَبَّرْنَا . ثُمَّ قَالَ " إِنِّي لأَرْجُو أَنْ تَكُونُوا شَطْرَ أَهْلِ الْجَنَّةِ وَسَأُخْبِرُكُمْ عَنْ ذَلِكَ مَا الْمُسْلِمُونَ فِي الْكُفَّارِ إِلاَّ كَشَعْرَةٍ بَيْضَاءَ فِي ثَوْرٍ أَسْوَدَ أَوْ كَشَعْرَةٍ سَوْدَاءَ فِي ثَوْرٍ أَبْيَضَ " .
Translation
Abdullah b. Mas'ud reported:The Messenger of Allah (ﷺ) addressing us said: Aren't you pleased that you should constitute one-fourth of the inhabitants of Paradise? He (the narrator) said: We glorified (our Lord, i. e. we called aloud Allah-o Akbar, Allah is the Greatest). He, then, again said: Aren't you pleased that you should constitute one-third of the inhabitants of Paradise? He (the narrator) said: We glorified (our Lord) and he (the Holy Prophet) then again said: I hope that you would constitute half of the inhabitants of Paradise and I shall explain to you its (reason). The believers among the unbelievers would not be more than a white hair on (the body of a) black ox or a black hair on (the body of a) white ox
