Mukhtasar Bukhari

Narrated Al-Bara' (may Allah be pleased with him): I saw the Prophet (peace and blessings of Allah be upon him) while Al-Hasan bin Ali (may Allah be pleased with him) was on his shoulder, and he (peace be upon him) was saying: "O Allah! I love him, so You also love him."

'Sayyiduna Anas (may Allah be pleased with him) says that' there was no one who resembled the Prophet Muhammad (peace and blessings be upon him) more than Sayyiduna Hasan bin Ali (may Allah be pleased with him).

Narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that a man from among the people of Iraq asked him: "If a person in the state of Ihram kills a fly?" So Sayyiduna Ibn Umar (may Allah be pleased with them both) said: "The people of Iraq ask about killing a fly, even though they killed the grandson of the Noble Prophet (peace and blessings of Allah be upon him), about whom the Noble Prophet (peace and blessings of Allah be upon him) said: 'These two are my flowers in this world.'"
