Yahya related to me from Malik from Alqama ibn Abi Alqama that his mother said, "Hafsa bint Abd ar-Rahman visited A'isha, the wife of the Prophet, may Allah bless him and grant him peace, and Hafsa was wearing a long thin head scarf. A'isha tore it in two and made a thick one for her."
Muwatta Malik Book 48, Hadith 7
