I'm currently a teen Sunni Muslim who wants to become a Shia. I have researched myself and found that my heart is on the Shia side of Islam and I agree with more of the Shia side. Although is there a process of becoming a Shia Muslim? My family is Sunni although I do not want to tell them yet. But I want to start living my life as a Shia Muslim e.g. Praying, Reading The Quran, etc.
To the best of my knowledge, there seem to be several items that you ought to pay heed to them (and factually perform them) to be a Shia Muslims, such as:
- Believing in Allah (the oneness of God) (which is common between
- Believing that Prophet Muhammad (pbuh) is the apostle of Allah (which is common between Shia/Sunni)
And actually Saying Shahadatayn (which is common between Shia/Sunni)...
Likewise, believing that Ali (a.s.) is the successor of the Prophet (peace be upon him and his household) (and also, other Shia Imams who...)
And following other Shia beliefs and practices, such as manner of Salah (saying-prayer), and so forth.
As another helpful issue(s):
You must believe in the Shia fundamentals of faith with your own insight and understanding. The Shia believe in five principles such as the Oneness of God, Prophet-hood of the Last Prophet (S), Resurrection, Divine Justice and Imamate.
Source and more accurate matters:
I hope this is not too late! That the Ummah listened to all Prophet's orders during his life is simply the opposite of truth! Read the Quran and see all the verses in which Allah rebukes "Muslims" for their hypocrisy, duplicity cowardice, wavering faith and all other forms of vice you can think of! Read this booklet by Ayatollah Sobhani for a commentary on these verses.
Indeed, given that Prophet Muhammad (pbuh) lived in a community where even his wives played tricks on him (research the story surrounding Surat at-Tahreem), how then one might expect that the rest of the Muslims might have all or most been nice and obedient people? In wars and peace "Muslims" caused trouble for the Prophet. In war, often the first trouble was not the enemy but the "believers" who were hesitant to fight and instead blamed the Prophet for bringing trouble upon them! In the Battle of Badr nearly whoever was killed on the enemy's side was killed by Ali ibn Abi Talib and Hamza ibn Abdul Muttalib! In the Battle of Uhud all except a dozen deserted the Battle in the beginning and in the end upon defeat! In the Battle of Ahzab nobody stepped forward to fight 'Amr ibn Abduwad except Ali. In the Battle of Khaibar nobody accepted to lead an army to Khaibar except Ali who came back victorious. Frequently they doubted and questioned His Divine ministry. His wives sometimes harassed him! Some companions conspired to murder him on his way from the Battle of Tabuk while some others were agitating Medina against his deputy Ali! He felt threatened by companions when he had to declare his successor at Ghadir Khumm and they were already busy arranging in secret to circumvent his guideline for succession soon after the event at Ghadir. On His death bed companions refused to allow him to write a last will, and we can go on and on!
So no! Things were not as rosy as you might have imagined during the life of the Holy Prophet at least according to the Shia narrative of early Islamic history! It was only that the Prophet was way too forgiving and magnanimous towards the people trying not to drive them from himself despite their malice however grave and inglorious, and he also knew that the failure of Muslims to live up to his true Sunnah was destined and unpreventable but he needed to clarify truth before his passing for those who were destined to recognize it.
But what do for your conversion now? I recommend you to continue with your studies! For this I recommend you books written by Allama Muhammad Tijani Samawi, a Tunisian scholar who converted from Sufism to Wahhabism and ultimately to Shiism! Until then you don't have to publicize your new madhhab. Continue to follow the Sunni law on matters of fiqh until you have 100 percent confidence in Shia Islam so that you are able to explain to your family why you chose to convert. But you'd better not bring up the highly controversial aspects of Sunni-Shia debate that may be too much to bear for your family. You may only focus on the virtues of Ahl Al-Bayt and how they are recognized by both Sunnis and Shias, and as for the doctrine of Imamate, just argue that the Sahaba were simply mistaken in ignoring Imam Ali (pbuh) as the immediate successor to the Prophet. Wish you a peaceful conversion!
You keep your family and Sunni friends, you don't go to them with your new ideology of Islam. If they had questions then you answer. If not be silent.
In addition: You have already said the shahadatyn so you were a Muslim and still will be.
You need to acknowledge the existence of Imam Mahdi as your current Imam (من لم یعرف امامه مات میته جاهلیه) and try to follow his way of living. In addition, you need to study and understand religion if you can't do that then you need to find yourself a marja' like what many others do and then learn their different ahkam (religious orders). Turning into a Shia may significantly change the way you think + lot's of small changes in Ahkam, like in way of prayers, wudu, time of adhan, etc.
If you want to be a Shia you should say
اشهد ان لا اله الا الله، اشهد ان محمد رسول الله، اشهد ان علی ولی الله If you said you are a shia.
