Narrated Asma: I prepared the journey-food for Allah's Apostle 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)).
