question #1 Sahih al-Bukhari 2982, Book 56, Hadith 191 : How did the Prophet Muhammad (ﷺ) address the issue of food scarcity among his companions during a journey?

Once the journey-food of the people ran short and they were in great need. So, they came to the
Prophet to take his permission for slaughtering their camels, and he permitted them. Then `Umar met
them and they informed him about it. He said, “What will sustain you after your camels (are
finished)?” Then `Umar went to the Prophet (ﷺ) and said, “O Allah’s Messenger (ﷺ)! What will sustain them
after their camels (are finished)?” Allah’s Messenger (ﷺ) said, “Make an announcement amongst the people
that they should bring all their remaining food (to me).” (They brought it and) the Prophet (ﷺ) invoked
Allah and asked for His Blessings for it. Then he asked them to bring their food utensils and the
people started filling their food utensils with their hands till they were satisfied. Allah’s Messenger (ﷺ) then
said, “I testify that None has the right to be worshipped but Allah, and I am His Apostle. ”
