Narrated Abu Maryam `Abdullah bin Ziyad Al-Aasadi:When Talha, AzZubair and `Aisha moved to Basra, `Ali sent `Ammar bin Yasir and Hasan bin `Ali who came to us at Kufa and ascended the pulpit. Al-Hasan bin `Ali was at the top of the pulpit and `Ammar was below Al-Hasan. We all gathered before him. I heard `Ammar saying, "`Aisha has moved to Al-Busra. By Allah! She is the wife of your Prophet in this world and in the Hereafter. But Allah has put you to test whether you obey Him (Allah) or her (`Aisha).
