Yahya related to me from Malik from Ismail ibn Abi Hakim from Sulayman ibn Yasar that Umar ibn al-Khattab went out early in the morning to his land in al-Juruf and found semen on his garment. He said, "I have been tried with wet dreams since I have been entrusted with governing the people." He did ghusl and washed his garment of what he saw of the semen, and then prayed after the sun had risen.

أَنَّ عُمَرَ بْنَ الْخَطَّابِ غَدَا إِلَى أَرْضِهِ بِالْجُرُفِ فَوَجَدَ فِي ثَوْبِهِ احْتِلاَمًا فَقَالَ لَقَدِ ابْتُلِيتُ بِالاِحْتِلاَمِ مُنْذُ وُلِّيتُ أَمْرَ النَّاسِ فَاغْتَسَلَ وَغَسَلَ مَا رَأَى فِي ثَوْبِهِ مِنَ الاِحْتِلاَمِ ثُمَّ صَلَّى بَعْدَ أَنْ طَلَعَتِ الشَّمْسُ

Yahya related to me from Malik from Yahya ibn Said from Sulayman ibn Yasar that Umar ibn al-Khattab led the people in the subh prayer and then went out to his land in Juruf and found semen on his clothes. He said, "Since we have been eating rich meat our veins have become fulsome." He did ghusl, washed the semen from his clothing, and did his prayer again.

أَنَّ عُمَرَ بْنَ الْخَطَّابِ صَلَّى بِالنَّاسِ الصُّبْحَ ثُمَّ غَدَا إِلَى أَرْضِهِ بِالْجُرُفِ فَوَجَدَ فِي ثَوْبِهِ احْتِلاَمًا فَقَالَ إِنَّا لَمَّا أَصَبْنَا الْوَدَكَ لاَنَتِ الْعُرُوقُ فَاغْتَسَلَ وَغَسَلَ الاِحْتِلاَمَ مِنْ ثَوْبِهِ وَعَادَ لِصَلاَتِهِ
