Jabir bin Abdullah reported,

The Messenger of Allah ﷺ dispatched an expedition toward the coast and placed Abu Ubayda bin al-Jarrah in command. They were three hundred men, and I was among them.We set out, and when we had gone part of the way, our provisions ran out. Abu Ubayda ordered that the remaining provisions of the army be gathered together, and all of it amounted to two sacks of dates. He would ration it out to us little by little each day, smaller and smaller portions, until it was nearly finished and we were each receiving only a single date.I said, "What good can a single date do?"He replied, "We truly felt its loss once it was gone." …the hadith continues.

عن جابر بن عبد الله، أنه قال

بعث رسول الله ﷺ بعثا قبل الساحل، فأمر عليهم أبا عبيدة بن الجراح وهم ثلاثمائة، قال: وأنا فيهم، قال: فخرجنا حتى إذا كنا ببعض الطريق فني الزاد، فأمر أبو عبيدة بأزواد ذلك الجيش، فجمع ذلك كله، فكان مزودي تمر، قال: فكان يقوتناه كل يوم قليلا قليلا حتى قليلا قليلا، حتى فني، ولم تصبنا إلا تمرة تمرة. فقلت: وما تغني تمرة؟ فقال: لقد وجدنا فقدها حين فنيت… الحديث.
