The Prophet ﷺ decreed that one should not eat two dates together at a time unless he gets the permission from his companions (sharing the meal with him).
سَمِعْتُ ابْنَ عُمَرَ ؓ يَقُولُ نَهَى النَّبِيُّ ﷺ أَنْ يَقْرُنَ الرَّجُلُ بَيْنَ التَّمْرَتَيْنِ جَمِيعًا حَتَّى يَسْتَأْذِنَ أَصْحَابَهُ
I heard Ibn 'Umar as saying that Messenger of Allah ﷺ forbade anyone taking two dates together without seeking the consent of his companions.
سَمِعْتُ ابْنَ عُمَرَ يَقُولُ نَهَى رَسُولُ اللَّهِ ﷺ أَنْ يَقْرِنَ الرَّجُلُ بَيْنَ التَّمْرَتَيْنِ حَتَّى يَسْتَأْذِنَ أَصْحَابَهُ
“The Messenger of Allah ﷺ forbade eating two dates at once unless he asks his companions permission to do so.”
سَمِعْتُ ابْنَ عُمَرَ يَقُولُ نَهَى رَسُولُ اللَّهِ ﷺ أَنْ يَقْرِنَ الرَّجُلُ بَيْنَ التَّمْرَتَيْنِ حَتَّى يَسْتَأْذِنَ أَصْحَابَهُ
“The Messenger of Allah ﷺ forbade eating two dates at once unless he asks his companions permission to do so.” (Using translation from Ibn Mājah 3331)
نَهَى رَسُولُ اللهِ ﷺ أَنْ يَقْرُنَ الرَّجُلُ بَيْنَ التَّمْرَتَيْنِ حَتَّى يَسْتَأْذِنَ أَصْحَابَهُ
