عَنْ يُونُسَ عَنِ الْحَسَنِ عَنْ أَبِي هُرَيْرَةَ أَنَّ رَجُلًا جَاءَ إِلَى النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فَقَالَ: إِنَّ فُلَانًا نَامَ الْبَارِحَةَ وَلَمْ يُصَلِّ شَيْئًا حَتَّى أَصْبَحَ، فَقَالَ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ: ((بَالَ الشَّيْطَانُ فِي أُذْنِهِ))، قَالَ يُونُسُ: وَقَالَ الْحَسَنُ: إِنَّ بَوْلَهُ وَاللَّهِ ثَقِيلٌ
It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that a man came to the Noble Prophet (peace and blessings be upon him) and said: "So-and-so slept through the night and did not pray until morning." The Prophet (peace and blessings be upon him) said: "Satan urinated in his ear." Hasan said: "By Allah! His urine must be very heavy."
