Narated By Umm al-Mundhar bint Qays al-Ansariyyah : The Apostle of Allah (pbuh) came to visit me, accompanied by Ali who was convalescing. We had some ripe dates hung up. The Apostle of Allah (pbuh) got up and began to eat from them.
Ali also got up to eat, but the Apostle of Allah (pbuh) said repeatedly to Ali: Stop, Ali, for you are convalescing, and Ali stopped.
She said: I then prepared some barley and beer-root and brought it. The Apostle of Allah (pbuh) then said: Take some of this, Ali, for it will be more beneficial for you. AbuDawud said: The narrator Harun said: al-Adawiyyah (i.e. Umm al-Mundhar).
