حَدَّثَنَا أَسْبَاطُ بْنُ مُحَمَّدٍ حَدَّثَنَا هِشَامُ بْنُ سَعْدٍ عَنْ عُبَيْدِ اللَّهِ بْنِ عَبَّاسِ بْنِ عَبْدِ الْمُطَّلِبِ أَخِي عَبْدِ اللَّهِ قَالَ كَانَ لِلْعَبَّاسِ مِيزَابٌ عَلَى طَرِيقِ عُمَرَ بْنِ الْخَطَّابِ فَلَبِسَ عُمَرُ ثِيَابَهُ يَوْمَ الْجُمُعَةِ وَقَدْ كَانَ ذُبِحَ لِلْعَبَّاسِ فَرْخَانِ فَلَمَّا وَافَى الْمِيزَابَ صُبَّ مَاءٌ بِدَمِ الْفَرْخَيْنِ فَأَصَابَ عُمَرَ وَفِيهِ دَمُ الْفَرْخَيْنِ فَأَمَرَ عُمَرُ بِقَلْعِهِ ثُمَّ رَجَعَ عُمَرُ فَطَرَحَ ثِيَابَهُ وَلَبِسَ ثِيَابًا غَيْرَ ثِيَابِهِ ثُمَّ جَاءَ فَصَلَّى بِالنَّاسِ فَأَتَاهُ الْعَبَّاسُ فَقَالَ وَاللَّهِ إِنَّهُ لَلْمَوْضِعُ الَّذِي وَضَعَهُ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالَ عُمَرُ لِلْعَبَّاسِ وَأَنَا أَعْزِمُ عَلَيْكَ لَمَّا صَعِدْتَ عَلَى ظَهْرِي حَتَّى تَضَعَهُ فِي الْمَوْضِعِ الَّذِي وَضَعَهُ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَفَعَلَ ذَلِكَ الْعَبَّاسُ رَضِيَ اللَّهُ تَعَالَى عَنْهُ
مسند امام احمد بن حنبل · Hadith 1790
It was narrated that 'Ubaidullah bin 'Abbas bin 'Abdul-Muttalib, the brother of 'Abdullah, said: Al-'Abbas had a downspout on the route taken by 'Umar bin al-Khattab. One Friday, 'Umar got dressed. Two chickens had been slaughtered for al- ' Abbas, and when ['Umar] passed by the downspout, water came out, mixed with blood of the two chickens. It landed on 'Umar, and in it was the blood of the two chickens. 'Umar ordered that the downspout be removed, then he went back and took off those clothes, and put on some other clothes. Then he came and led the people in prayer. Al-'Abbas came to him and said: By Allah, the downspout is where the Prophet (PBUH) put it. So 'Umar said to al- 'Abbas: I insist that you should climb onto my back and put it where the Messenger of Allah (PBUH) put it. So al-' Abbas (RA) did that.
