(4) باب الْقِرَانِ فِي التَّمْرِ بَيْنَ الشُّرَكَاءِ حَتَّى يَسْتَأْذِنَ أَصْحَابَهُ
Narrated Jabala:
"While at Medina we were struck with famine. Ibn Az-Zubair used to provide us with dates as our food. Ibn `Umar used to pass by us and say, "Don't eat two dates together at a time as the Prophet (ﷺ) has forbidden eating two dates together at a time (in a gathering) unless one takes the permission of one's companion brother."
