[Machine] While the Messenger of Allah ﷺ was holding my hand on a certain path for eighteen nights that had passed from Ramadan, he saw a man who was performing 'Ihtijam', so he said, "The one who performs 'Ihtijam' and the one on whom it is performed both break their fast." Abu 'Abdur-Rahman 'Abbad bin Mansur compiled both narrations and said that Abu Asma’ Thawban and Abu Al-Ash'ath narrated from Shaddad bin Aws.  

الكبرى للنسائي:٣١٢٧أَخْبَرَنَا إِسْمَاعِيلُ قَالَ حَدَّثَنَا عَاصِمُ بْنُ هِلَالٍ عَنْ أَيُّوبَ عَنْ أَبِي قِلَابَةَ عَنْ أَبِي أَسْمَاءَ عَنْ شَدَّادِ بْنِ أَوْسٍ قَالَ

بَيْنَمَا رَسُولُ اللهِ ﷺ آخِذٌ بِيَدِي فِي بَعْضِ الطَّرِيقِ لِثَمَانَ عَشْرَةَ لَيْلَةً خَلَتْ مِنْ رَمَضَانَ فَأَبْصَرَ رَجُلًا يَحْتَجِمُ فَقَالَ «أَفْطَرَ الْحَاجِمُ وَالْمَحْجُومُ» قَالَ أَبُو عَبْدِ الرَّحْمَنِ عَبَّادُ بْنُ مَنْصُورٍ جَمَعَ بَيْنَ الْحَدِيثَيْنِ فَقَالَ عَنْ أَبِي أَسْمَاءَ عَنْ ثَوْبَانَ وَعَنْ أَبِي الْأَشْعَثِ عَنْ شَدَّادِ بْنِ أَوْسٍ
