It was narrated from Anas bin Malik that the Messenger of Allah (ﷺ) prayed ‘Eid at the prayer place, using a small spear as a Sutrah.
Sunan Ibn Majah Book 5, Hadith 504
← Previous Hadith “When the Prophet (ﷺ) prayed on the day of ‘Eid or on another occasion, a small spear was set up in front of him, and he prayed facing it, and the people were behind him.”

Nafi` said: It is from here that the leaders have taken this practice.

Sunan Ibn Majah Book 5, Hadith 503 Next Hadith → “The Messenger of Allah (ﷺ) commanded us to bring them (the women) out on the day of Fitr and the day of Nahr.” Umm ‘Atiyyah said: “We said: ‘What if one of them does not have an outer covering?’ He said: ‘Let her sister share her own outer covering with her.’”
