Sahih al-Bukhari Book 78, Hadith 25
I was present when a man asked Ibn `Umar about the blood of mosquitoes. Ibn `Umar said, "From
where are you?" The man replied. "From Iraq." Ibn `Umar said, "Look at that! he is asking me about
the blood of Mosquitoes while they (the Iraqis ) have killed the (grand) son of the Prophet. I have
heard the Prophet (ﷺ) saying, "They (Hasan and Husain) are my two sweet-smelling flowers in this
world."
Um Khalid bint Khalid bin Sa`id said, "I came to Allah's Messenger (ﷺ) along with my father and I was wearing a yellow shirt. Allah's Messenger (ﷺ) said, "Sanah Sanah!" (`Abdullah, the sub-narrator said, "It means, 'Nice, nice!' in the Ethiopian language.") Um Khalid added, "Then I started playing with the seal of Prophethood. My father admonished me. But Allah's Messenger (ﷺ) said (to my father), "Leave her," Allah's Messenger (ﷺ) (then addressing me) said, "May you live so long that your dress gets worn out, and you will mend it many times, and then wear another till it gets worn out (i.e. May Allah prolong your life)." (The sub-narrator, `Abdullah aid, "That garment (which she was wearing remained usable for a long period.").
(the wife of the Prophet) A lady along with her two daughters came to me asking me (for some alms), but she found nothing with me except one date which I gave to her and she divided it between her two daughters, and then she got up and went away. Then the Prophet (ﷺ) came in and I informed him about this story. He said, "Whoever is in charge of (put to test by) these daughters and treats them generously, then they will act as a shield for him from the (Hell) Fire."
