Musannaf Ibn Abi Shaybah

It is narrated from Hazrat Umm Salamah. She says that the Noble Prophet Muhammad (peace and blessings be upon him) was asked: How much can a woman lengthen her garment? He (peace and blessings be upon him) said: "A span." The questioner said: Then a woman's body will be exposed. He (peace and blessings be upon him) said: "Then a forearm's length, but no more than that."

It is narrated from Hazrat Ibn Umar (may Allah be pleased with them both) that the noble wives of the Prophet Muhammad (peace and blessings be upon him) were permitted to extend their garments by one handspan. So they would come to us and we would measure for them one cubit using a cane.

It is narrated from Hazrat Hasan that the Noble Prophet Muhammad (peace and blessings be upon him and his family) measured a span for Hazrat Fatimah and said: "This is the measure of your garment."

It is narrated from Hazrat Abu Huraira that the Noble Prophet Muhammad (peace and blessings be upon him) said to Hazrat Fatimah or Hazrat Umm Salamah: "Your lower garment is one hand span."

Hazrat Ismail bin Abu Khalid narrates about Hazrat Yunus bin Abu Khalid that he used to instruct that a woman should make her lower garment one hand span long.
