Maliks Muwatta Book 45, Hadith Number 3.

Section : Residing in Madina and Leaving It.

Yahya related to me from Malik from Qatan ibn Wahb ibn Umayr ibn al-Ajda that Yuhannas, the mawla of az-Zubayr ibn al-Awwam informed him that he was sitting with Abdullah ibn Umar during the troubles (at the time of al-Hajaj ibn Yusuf). A female mawla of his came and greeted him. She said, “I want to leave, Abu Abd ar-Rahman. The time is harsh for us.” Abdullah ibn Umar said to her, “Sit down, O you with little knowledge, for I have heard the Messenger of Allah, may Allah bless him and grant him peace, say, ‘No one will be patient in hunger and hardship in it (Madina) except that I will be a witness or intercede for him on the Day of Rising.'”
