I prepared provisions for the Prophet ﷺ and Abu Bakr when they intended to set out for Medina. I said to my father, "I cannot find anything to tie it with except my waistband."He said, "Tear it in two."So I did, and from that I was called Dhat al-Nitaqayn, the one with two waistbands.
صنعت سفرة للنبي ﷺ وأبي بكر حين أرادا المدينة، فقلت لأبي: ما أجد شيئا أربطة إلا نطاقي، قال: فشقيه، ففعلت فسميت ذات النطاقين.
Bukhari related it in the Book of Virtues (3907) from Abdullah bin Abu Shayba, who said, Abu Usama narrated to us, Hisham narrated to us, from his father and Fatimah, from Asma, and he mentioned it. Fatimah is the daughter of Mundhir bin Zubayr bin Awwam, the wife of Hisham bin Urwa.
