Thabit (may Allah be pleased with him) narrated from Anas (may Allah be pleased with him) that the Prophet (peace and blessings of Allah be upon him) took (his son) Ibrahim (may Allah be pleased with him) in his lap, kissed him, and smelled him.

Narrated Ibn Abi Na'm: 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 saying, "They (Hasan and Husain) are my two sweet-smelling flowers in this world."
