Hadith 5641
Anas told that when God's messenger was asked what al-Kauthar[*] was he replied, "That is a river God has given me (meaning in paradise), whiter than milk and sweeter than honey, containing birds whose necks are like the necks of sacrificial camels." `Umar remarked, "These have a pleasant life," and God's messenger replied, "Those who eat them have a pleasanter life." *Quran; 108 Tirmidhi transmitted it.
وَعَنْ أَنَسٍ قَالَ سُئِلَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ماالكوثر؟ قَالَ: «ذَاكَ نَهْرٌ أَعْطَانِيهِ اللَّهُ يَعْنِي فِي الْجَنَّةِ أَشَدُّ بَيَاضًا مِنَ اللَّبَنِ وَأَحْلَى مِنَ الْعَسَلِ فِيهِ طَيْرٌ أَعْنَاقُهَا كَأَعْنَاقِ الْجُزُرِ» قَالَ عُمَرُ: إِنَّ هَذِهِ لَنَاعِمَةٌ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ «أَكَلَتُهَا أَنْعَمُ مِنْهَا» رَوَاهُ التِّرْمِذِيّ
