So, I said to Abu Bakr, "By Allah, I do not find anything to tie (these things) with except my waist belt." He said, "Cut it into two pieces and tie the water-skin with one piece and the food-container with the other (the subnarrator added, "She did accordingly and that was the reason for calling her Dhatun-Nitaqain (i.e. twobelted woman)).

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. "
