Mishkat al-Masabih

‘Ikrima, on the authority of Ibn ‘Abbas, said the Prophet (ﷺ) forbade that the food of two people who were rivalling one another should be eaten. Abu Dawud transmitted it. Muhyi as-Sunna said the sound version is that it comes from ‘Ikrima from the Prophet (ﷺ) in mursal form.

وَعَنْ عِكْرِمَةَ عَنِ ابْنِ عَبَّاسٍ: أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ نَهَى عَنْ طَعَامِ الْمُتَبَارِيَيْنِ أَنْ يُؤْكَلَ. رَوَاهُ أَبُو دَاوُدَ وَقَالَ مُحْيِي السُّنَّةِ: وَالصَّحِيحُ أَنَّهُ عَنْ عِكْرِمَةَ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مُرْسَلًا
