Abdullah ibn Amr reported: The Messenger of Allah, peace and blessings be upon him, said, “My fountain is like the distance between ‘Adan and ‘Amman, cooler than ice, sweeter than honey, its fragrance more pleasant than musk, its cups as numerous as stars in the sky. Whoever drinks from it will never be thirsty afterward forever. The first people to arrive at it are homeless among the emigrants.” Someone said, “Who are they, O Messenger of Allah?” The Prophet said, “Their hair is disheveled, their faces disfigured, and their clothes stained. The gates of the rulers are not opened for them and they are not favored in marriage, yet they fulfill every right over them and do not take any right belonging to them.”

عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ حَوْضِي كَمَا بَيْنَ عَدَنَ وَعَمَّانَ أَبْرَدُ مِنَ الثَّلْجِ وَأَحْلَى مِنَ الْعَسَلِ وَأَطْيَبُ رِيحًا مِنَ الْمِسْكِ أَكْوَابُهُ مِثْلُ نُجُومِ السَّمَاءِ مَنْ شَرِبَ مِنْهُ شَرْبَةً لَمْ يَظْمَأْ بَعْدَهَا أَبَدًا أَوَّلُ النَّاسِ عَلَيْهِ وُرُودًا صَعَالِيكُ الْمُهَاجِرِينَ قَالَ قَائِلٌ وَمَنْ هُمْ يَا رَسُولَ اللَّهِ قَالَ الشَّعِثَةُ رُءُوسُهُمْ الشَّحِبَةُ وُجُوهُهُمْ الدَّنِسَةُ ثِيَابُهُمْ لَا يُفْتَحُ لَهُمْ السُّدَدُ وَلَا يَنْكِحُونَ الْمُتَنَعِّمَاتِ الَّذِينَ يُعْطُونَ كُلَّ الَّذِي عَلَيْهِمْ وَلَا يَأْخُذُونَ الَّذِي لَهُمْ
