Musannaf Ibn Abi Shaybah

Hazrat Abdul Wahid bin Safwan narrates. He says that I heard my father, who narrated from his mother, that she said: I used to soak raisins for Hazrat Uthman in the morning, which he would drink in the evening, and (similarly) I used to soak raisins for him in the evening, which he would drink in the morning. Then Hazrat Uthman (one day) said to her (the lady Safiyyah): Perhaps you also add dates to it? She replied: Sometimes I do this. So Hazrat Uthman said: Do not do this.
