Who's a true Shia? Hadith 1

Jabir narrates that Abu Ja’far (Imam Baqir) said: “Is it enough for
a person to (merely) embellish (oneself) as a Shia by professing love
of us, Ahlul-Bait? Nay! By Allah, a person is not our follower except
the one who fears Allah and obeys Him. O' Jabir! Our followers are
not recognized save by humility, submission, honesty, praising Allah
abundantly, fasting and prayers, attending to the poor, needy,
debtors and orphans who live near him, saying the truth, reciting the
Qur'an, withholding the tongue from people except for benediction;
and being trustworthy to their relatives in any affairs."
Jabir asked: "O son of the Messenger of Allah! I do not know
anybody with these traits."
Imam Baqir said: "O' Jabir! Do not let the various sects affect
you. Do you think that it suffices for one to say that he likes Imam
Ali and he is his follower, but does not do anything to support his
claim? Or he says that he likes the Prophet , who is even better
than Imam Ali , but does not take his example and follow his
deeds and act according to the Prophet's tradition. Just having love
for the Prophet is of no use for him. Therefore fear God, and act in
such a way as to attain what is near God, since there is no relation
of kin between God and anyone. The one most loved by God is the
one who is the most pious, and the noblest one is the one who fears
God and obeys Him. I swear by God that it is not possible to get
close to God unless by His obedience, and we do not hold the key to
relief from the Fire of Hell, and no one has any authority over God.
Whoever is obedient to God is our friend, and whoever disobeys God
is our enemy. No one can attain our friendship unless by having
nobility and piety."5
