Musannaf Ibn Abi Shayba 33:247

Abu Usama narrated to us, he said: Hisham ibn Urwa informed us, from his father, who said: When Umar arrived in Ash-Sham, his shirt had become worn out at his seat; it was a thick Sunbulani shirt. So he sent it to the governor of Adhri'at or Ubla. He (the governor) washed it, patched it, and sewed a Qatari shirt for him. He brought both of them to him and threw the Qatari one to him. Umar took it, touched it, and said: "This is softer." Then he threw it back to him and said: "Throw my shirt to me, for it is more absorbent of sweat."
