Sayyidah Umm Salamah (may Allah be pleased with her) narrates: The Prophet (peace and blessings be upon him) used to offer prayer on a mat.
Imam Abu Ya'la recorded it, and Tabarani in al-Mu'jam al-Kabir and al-Mu'jam al-Awsat; however, he narrated these words in it: "The Prophet (peace and blessings be upon him) had a mat on which he would offer prayer." Imam Abu Ya'la's narrators are the narrators of the Sahih.
