Imam Hussain (رضی اﷲ عنہ)
Imam hussain(رضی اﷲ عنہ): Allah Almighty made Karbala an everlasting life and a living, so that humans and especially believers should take lessons. Hazrat Imam Hussain رضی اﷲ عنہ was born on 5th Shaban 4 Hijri in Madina Taiba. The Prophet ﷺ gave Azan in His ear, put the Laub Dahan in the mouth and prayed for him, then on the seventh day, names Him Hussain. Hazrat Hussain (رضی اﷲ عنہ) was known by Abu Abdullah and title was Sibat e Rasool.
In Hadith Sharif, The Messenger of Allah (ﷺ) said that Haroon علیہ السلام named his sons Shabir and Shabber, and I kept my sons name Hassan and Hussain on their names. (صواعق محرقہ, p. 118)
Therefore, Hassnain Karimain is also remembered by Shabir and Shabbar. In Syriac language Shabir and Shabbar and in Arabic and Hassan and Hussain.
In a Hadith these two names Hassan and Hussain are from Havens names (صواعق محرقه, p. 1186)
Ibn al-Arbi quotes from Hazrat Mufsil says: "Allah Almighty has places these secretly even though the Prophet (ﷺ) named the names of his grandson Hassan and Hussain." (اشرف المؤید, p. 70)
Hussain(رضی اﷲ عنہ) is from Me (ﷺ)
It is narrated from Hazrat Yaali bin Marrah( یعلی بن مرہ) that the Prophet (ﷺ) said: "Hussain(رضی اﷲ عنہ) is from me (ﷺ) and I (ﷺ) am from Hussain(رضی اﷲ عنہ) (Tirmazhi Sharif)
It means Hussain(رضی اﷲ عنہ) is too much close to Prophet ﷺ because both of them are one. The mentioning of Hussain(رضی اﷲ عنہ) is the mentioning Prophet (ﷺ). Friend of Hussain is Friend of Prophet ﷺ. Enemy of Hussain is Enemy of Prophetﷺ.
Love of Allah, Rasool ﷺ, Hussain (رضی اﷲ عنہ)
The Prophet (peace and blessings of Allah be upon him) said: "Whoever loves Hussain (رضی اﷲ عنہ) he loves Holy Prophet (ﷺ) and loving the Prophet (ﷺ) is to love Allah Almighty. (مشکوۃ شریف p. 571)
Abu Hurairah (رضی اﷲ عنہ) said: "The Messenger of Allah (ﷺ) came to the Masjid and said," Where is the little child? " Hazrat Imam Hussain رضی اﷲ عنہ came and sat in the lap of the Holy Prophet (ﷺ) and enter his fingers in the blessed beard The Prophet (ﷺ) kissed his face and kissed him and said, “O God, I love Him, You also love him and also love those who love him. (نور الابصار p. 114)
Its mean Hazrat Muhammad(ﷺ) not only loves him, but also said to Allah to love him and love those who love him.
The leader of the young men of heavens, Prophet's (ﷺ) Son
It is narrated from Imam Hussain (رضی اﷲ عنہ) that the Prophet ((ﷺ)) said, "Whoever wants to look leader of the Jannah (heaven), he sees Hussain bin Ali (رضی اﷲ عنہ)h ". (نور الابصار P. 114)

Hazrat Abdullah bin Umar (رضی اﷲ عنہ) was sitting in the shadow of Ka'bah. When he saw Imam Hussain (رضی اﷲ عنہ) coming. He said, today He is more beloved near sky people (Angels) than the earthly people.
Abu Saeed khadri (may Allah be pleased with him) said, "The Messenger of Allah (peace and blessings of Allah be upon him) said," Hassan and Hussain are leaders of Young men of Havens.(مشکوۃشریف p. 570)
