The Shias of Ahlul Bayt (a.s.)

One of the traditions concerning the position of the Shias and the lovers of Ahlul Bayt (a.s.) states that the fire of Hell cannot scorch them. Thus, these types of traditions impart strength to our hope. Our love for the Ahlul Bayt (a.s.) is certainly a surety for us but it should not tempt us to commit sins blatantly. 

Shia and Mohib

The traditions regarding this subject are based on two important points. The first is concerned with 'Shia' and the second 'Mohibs' (Admirers) of the Holy Ahlul Bayt (a.s.). The position and status of those Shias who have achieved excellence in the field of knowledge and good deeds is definitely higher. Even so, such people did not consider themselves fit to be called the Shias of Ahlul Bayt (a.s.). Take the example of Muhammad bin Muslim Thaqafi. He was the honourable companion (Sahaabi) of Imam Muhammad Baqir (a.s.) and Imam Ja'far as-Sadiq (a.s.). Both the Holy Imams (a.s.) have recommended him to the Shias for solving their religious problems. Muhammad bin Muslim Thaqafi has also been mentioned as the greatest Jurist of his time in the books of Rijal (Chain of narrators).

On one occasion Muhammad bin Muslim along with Abu Karibatul Azdi went to see Qazi Shareek. Shareek glared at him in anger and said, "These two are Ja'fari and Fatimi!" [Shias of Ahlul Bayt (a.s.)]. Upon hearing this, both of them began to cry bitterly. When the Qazi enquired the reason for their lamentation, they replied, "You have associated us with such a lofty personality [Imam Ja'far as-Sadiq (a.s.)]!. Are people like us who lack in piety and abstinence to be compared with such an exalted person? What connection does the dust have with the Divine existence? (A Persian saying). We shall be highly obliged to you if you can accept our request (and give us not the title that we do not deserve)." 

The True Shias are Those Who Follow (Obey) the Imams (a.s.)

Yes, we can give the title of 'Shia' to that individual who follows the Imams (a.s.) in all aspects of character and speech. Thus, Bab-ul-Hawaij Imam Musa al-Kazim (a.s.) says:
"Our shias are only those who follow us (in every respect), walk in our footsteps and imitate our actions."
(Behaarul Anwaar) 

Conversation of Ali (a.s.) With Some Shias

On a certain evening Ali (a.s.) was departing from the mosque. The surroundings were bright due to the moonlight. He saw behind him a group of people walking towards him. He enquired as to who they were? They said: "We are your Shias." Ali (a.s.) looked at their faces carefully and said.

"Why is it that your faces do not exhibit any sign of you being a Shia?".

"Master, what are the signs of a Shia?"

"Their faces are pale due to excessive worship and the fear of Allah, their backs are bent due to prolonged prayers, too much fasting causes their abdomen to touch their backbones, their lips become dry be repeating endless invocations, and their hearts are filled with the fear of Allah."
(Behaarul Anwaar, Al-Irshad).
Now I shall quote three traditions for the benefit of the readers:

Mere Claim is not Sufficient

1) Jabir (a.r.) relates from Imam Ja'far as-Sadiq (a.s.) that he said,
"Is it sufficient for one to associate himself with Shiaism and say that, "I am a lover of Ahlul Bayt (a.s.)? By Allah, our Shia is not, but the one who fears Allah and obeys His Commands."
(Al-Kafi)

2) Imam Ja'far as-Sadiq (a.s.) told Mufazzal bin Umar,
"If you wish to see one of our devotees then look for that person who abstains from sins and fears more His Creator and remains hopeful of His reward. Whenever you find such an individual then take it for granted that he is one of my devotees."

3) Isa bin Abdulla Qummi entered in the presence of Imam Ja'far as-Sadiq (a.s.). The Imam said,
"That person is not from us nor do we hold him in esteem, the one who, if he lives in a town of a population of hundred thousand and there is even one non-Shia who is more pious than him."
(Al-Kafi).

Thus the belief, actions and the piety of the Shias of Ahlul Bayt (a.s.) should be such that they should be the best and none should excel them. Allah has defined such people 'Khairul Bareeya' in the Holy Qur'an:
"(As For) those who believe and do good, surely they are the best of men."
(Surah Bayyanah 98:7)

The Holy Prophet (s.a.w.s.) is reported to have explained that 'Khairul Bareeya' connotes the Shias of Ali (a.s.):
"O Ali, 'Khairul Bareeya' means you and your Shias. On the Day of Judgement, they would be satisfied with what Allah has bestowed upon them and they shall be liked by Allah. (Tafseer Tabarsi, Manaqib Khwaarazmi, Ibne Hajar).
