Arabic (Original)
حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ عَنْ إِسْمَاعِيلَ بْنِ أُمَيَّةَ عَمَّنْ حَدَّثَهُ عَنْ أُمِّ وَلَدِ أُبَيِّ بْنِ كَعْبٍ عَنْ أُبَيِّ بْنِ كَعْبٍ أَنَّهُ دَخَلَ رَجُلٌ عَلَى النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالَ مَتَى عَهْدُكَ بِأُمِّ مِلْدَمٍ وَهُوَ حَرٌّ بَيْنَ الْجِلْدِ وَاللَّحْمِ قَالَ إِنَّ ذَلِكَ لَوَجَعٌ مَا أَصَابَنِي قَطُّ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مَثَلُ الْمُؤْمِنِ مَثَلُ الْخَامَةِ تَحْمَرُّ مَرَّةً وَتَصْفَرُّ أُخْرَى.
English Translation
Sufyan ibn Uyaynah narrated to us, from Isma'il ibn Umayyah, from someone who related to him, from the mother of Ubayy ibn Ka'b's child (umm walad), from Ubayy ibn Ka'b, that a man came to the Prophet, peace and blessings be upon him, and said: "When did you last have a fever, that heat between the skin and the flesh?" He said: "Indeed that is a pain the like of which has never afflicted me." The Messenger of Allah, peace and blessings be upon him, said: "The believer is like a young, tender plant: it reddens at times and yellows at other times."
