Jabala reported,

We were in Medina when a year of drought struck us. Ibn Zubayr used to provide us with dates as our ration, and Ibn Umar would pass by us and say, "Do not eat dates two at a time, for the Prophet ﷺ forbade pairing them unless one of you seeks permission from his companion."

Bukhari 2490

Sahih

حدثنا أبو الوليد حدثنا شعبة

عن جبلة قال

كنا بالمدينة فأصابتنا سنة فكان ابن الزبير يرزقنا التمر وكان ابن عمر يمر بنا فيقول لا تقرنوا فإن النبي ﷺ نهى عن الإقران إلا أن يستأذن الرجل منكم أخاه
