I prepared the journey-food for Messenger of Allah ﷺ in Abu Bakr's house when he intended to emigrate to Medina. I could not find anything to tie the food-container and the water skin with. 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)).  

صَنَعْتُ سُفْرَةَ رَسُولِ اللَّهِ ﷺ فِي بَيْتِ أَبِي بَكْرٍ حِينَ أَرَادَ أَنْ يُهَاجِرَ إِلَى الْمَدِينَةِ قَالَتْ فَلَمْ نَجِدْ لِسُفْرَتِهِ وَلاَ لِسِقَائِهِ مَا نَرْبِطُهُمَا بِهِ فَقُلْتُ لأَبِي بَكْرٍ وَاللَّهِ مَا أَجِدُ شَيْئًا أَرْبِطُ بِهِ إِلاَّ نِطَاقِي قَالَ فَشُقِّيهِ بِاثْنَيْنِ فَارْبِطِيهِ بِوَاحِدٍ السِّقَاءَ وَبِالآخَرِ السُّفْرَةَ فَفَعَلْتُ فَلِذَلِكَ سُمِّيَتْ ذَاتَ النِّطَاقَيْنِ  

During the life-time of the Prophet ﷺ we used to take the meat of sacrificed animals (as journey food) to Medina. (See Hadith No. 474 Vol. 7)  

كُنَّا نَتَزَوَّدُ لُحُومَ الأَضَاحِيِّ عَلَى عَهْدِ النَّبِيِّ ﷺ إِلَى الْمَدِينَةِ  

That he went out in the company o; the Prophet ﷺ during the year of Khaibar (campaign till they reached a place called As-Sahba', the lower part of Khaibar. They offered the ʿAsr prayer (there) and the Prophet asked for the food. Nothing but Sawiq was brought to the Prophet. So, they chewed it and ate it and drank water. After that the Prophet ﷺ got up, washed his mouth, and they too washed their mouths and then offered the prayer.  

أَخْبَرَهُ أَنَّهُ خَرَجَ مَعَ النَّبِيِّ ﷺ عَامَ خَيْبَرَ حَتَّى إِذَا كَانُوا بِالصَّهْبَاءِ وَهْىَ مِنْ خَيْبَرَ وَهْىَ أَدْنَى خَيْبَرَ فَصَلَّوُا الْعَصْرَ فَدَعَا النَّبِيُّ ﷺ بِالأَطْعِمَةِ فَلَمْ يُؤْتَ النَّبِيُّ ﷺ إِلاَّ بِسَوِيقٍ فَلُكْنَا فَأَكَلْنَا وَشَرِبْنَا ثُمَّ قَامَ النَّبِيُّ ﷺ فَمَضْمَضَ وَمَضْمَضْنَا وَصَلَّيْنَا  

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 ʿUmar met them and they informed him about it. He said, "What will sustain you after your camels (are finished)?" Then ʿUmar went to the Prophet ﷺ and said, "O Messenger of Allah ﷺ! What will sustain them after their camels (are finished)?" Messenger of Allah 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. Messenger of Allah ﷺ then said, "I testify that None has the right to be worshipped but Allah, and I am His Apostle. "  

خَفَّتْ أَزْوَادُ النَّاسِ وَأَمْلَقُوا فَأَتَوُا النَّبِيَّ ﷺ فِي نَحْرِ إِبِلِهِمْ فَأَذِنَ لَهُمْ فَلَقِيَهُمْ عُمَرُ فَأَخْبَرُوهُ فَقَالَ مَا بَقَاؤُكُمْ بَعْدَ إِبِلِكُمْ فَدَخَلَ عُمَرُ عَلَى النَّبِيِّ ﷺ فَقَالَ يَا رَسُولَ اللَّهِ مَا بَقَاؤُهُمْ بَعْدَ إِبِلِهِمْ قَالَ رَسُولُ اللَّهِ ﷺ نَادِ فِي النَّاسِ يَأْتُونَ بِفَضْلِ أَزْوَادِهِمْ فَدَعَا وَبَرَّكَ عَلَيْهِ ثُمَّ دَعَاهُمْ بِأَوْعِيَتِهِمْ فَاحْتَثَى النَّاسُ حَتَّى فَرَغُوا ثُمَّ قَالَ رَسُولُ اللَّهِ ﷺ أَشْهَدُ أَنْ لاَ إِلَهَ إِلاَّ اللَّهُ وَأَنِّي رَسُولُ اللَّهِ
