Narrated Asma: I prepared the journey food for the Prophet and Abu Bakr when they wanted (to migrate to) Medina. I said to my father (Abu Bakr), I do not have anything to tie the container of the journey food with except my waist belt. He said, Divide it lengthwise into two. I did so, and for this reason I was named 'Dhat-un-Nitaqain' (i.e. the owner of two belts). (Ibn `Abbas said, Asma', Dhat-un-Nitaq. )
