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

Allah's Messenger (ﷺ) (then addressing me) said, "May you live so long that your dress gets worn out, and

What do you think about my good deeds which I used to do during the period of ignorance (before embracing Islam) like keeping good relations with my Kith and kin, manumitting of slaves and giving alms etc; Shall I receive the reward for that?" Allah's Messenger (ﷺ) said, "You have embraced Islam with all those good deeds which you did.
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."
