The Prophet (ﷺ) paid a visit to Um-Sulaim and she placed before him dates and ghee. The Prophet (ﷺ) said, "Replace the ghee and dates in their respective containers for I am fasting." Then he stood somewhere in her house and offered an optional prayer and then he invoked good on Um-Sulaim and her family. Then Um-Sulaim said, "O Allah's Messenger (ﷺ)! I have a special request (today)." He said, "What is it?" She replied, "(Please invoke for) your servant Anas." So Allah's Messenger (ﷺ) did not leave anything good in the world or the Hereafter which he did not invoke (Allah to bestow) on me and said, "O Allah! Give him (i.e. Anas) property and children and bless him." Thus I am one of the richest among the Ansar and my daughter Umaina told me that when Al-Hajjaj came to Basra, more than 120 of my offspring had been buried.

Sahih al-Bukhari Book 30, Hadith 88 Next Hadith → That the Prophet (ﷺ) asked him (Imran) or asked a man and `Imran was listening, "O Abu so-and-so! Have you fasted the last days of this month?" (The narrator thought that he said, "the month of Ramadan"). The man replied, "No, O Allah's Messenger (ﷺ)!" The Prophet (ﷺ) said to him, "When you finish your fasting (of Ramadan) fast two days (in Shawwal)." Through another series of narrators `Imran said, "The Prophet (ﷺ) said, '(Have you fasted) the last days of Sha'ban?"
