Sahih Muslim Book - 1, Hadith - 531

حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ نُمَيْرٍ حَدَّثَنَا أَبِي حَدَّثَنَا مَالِكٌ وَهُوَ ابْنُ مِغْوَلٍ عَنْ أَبِي إِسْحَاقَ عَنْ عَمْرِو بْنِ مَيْمُونٍ عَنْ عَبْدِ اللَّهِ قَالَ خَطَبَنَا رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَأَسْنَدَ ظَهْرَهُ إِلَى قُبَّةِ أَدَمٍ فَقَالَ أَلَا لَا يَدْخُلُ الْجَنَّةَ إِلَّا نَفْسٌ مُسْلِمَةٌ اللَّهُمَّ هَلْ بَلَّغْتُ؟ اللَّهُمَّ اشْهَدْ أَتُحِبُّونَ أَنَّكُمْ رُبُعُ أَهْلِ الْجَنَّةِ فَقُلْنَا نَعَمْ يَا رَسُولَ اللَّهِ فَقَالَ أَتُحِبُّونَ أَنْ تَكُونُوا ثُلُثَ أَهْلِ الْجَنَّةِ قَالُوا نَعَمْ يَا رَسُولَ اللَّهِ قَالَ إِنِّي لَأَرْجُو أَنْ تَكُونُوا شَطْرَ أَهْلِ الْجَنَّةِ مَا أَنْتُمْ فِي سِوَاكُمْ مِنْ الْأُمَمِ إِلَّا كَالشَّعْرَةِ السَّوْدَاءِ فِي الثَّوْرِ الْأَبْيَضِ أَوْ كَالشَّعْرَةِ الْبَيْضَاءِ فِي الثَّوْرِ الْأَسْوَدِ.

It was narrated that 'Abdullah said: "The Messenger of Allah (s.a.w) addressed us and leaned his back against a leather tent. He said: 'No one will enter Paradise but a Muslim soul. O Allah, have I conveyed (the message)? O Allah, bear witness! Would you like to be one-quarter of the people of Paradise?' They said: 'Yes, O Messenger of Allah!' He said: 'Would you like to be one-third of the people of Paradise?' They said: 'Yes, O Messenger of Allah!' He said: 'I hope that you will be half of the people of Paradise, for among other nations you are like a black hair on a white bull, or like a white hair on a black bull."'
