The Book About the Etiquette of Eating
Prohibition of Eating Two Dates Simultaneously
عَنْ جَبَلَةَ بْنِ سُحَيْمٍ قَالَ: أَصَابَنَا عَامُ سَنَةٍ مَعَ ابْنِ الزُّبَيْرِ، فَرَزَقَنَا تَمْرًا، وَكَانَ عَبْدُ اللَّهِ بْنُ عُمَرَ رضى اللَّه عَنْهُمَا يَمُرُّ بِنَا وَنَحْنُ نَأْكُلُ، فيقول: لا تقارونوا، فإن النبى نهى عَنْ الإقران، ثُمَّ يَقُولُ: إِلاَّ أَنْ يَسْتَأْذِنَ الرَّجُلُ أَخَاهُ ((مُتَّفَقٌ عَلَيْهِ))
Jabalah bin Suhaim reported: We were with 'Abdullah bin Az-Zubair (May Allah be pleased with them) in a time of famine, then we were provided with dates. (Once) when we were eating, 'Abdullah bin 'Umar (May Allah be pleased with them) passed by us and said: "Do not eat two dates together, for Messenger of Allah (ﷺ) prohibited it, unless one seeks permission from his brother (partner)." [Al-Bukhari and Muslim].
