Therefore...
Therefore, your responsibility in the sight of Allah is based on the capability given to you from intellect, body, soul, spirit and His guidance to you in the ways of faith, action and favors. The way of knowing this responsibility can be achieved through: Intellect, Allah's book, the traditions of the Holy Prophet (s.a.w.) and the high feeling of responsibility. 2- Responsibility of Accepting Islam: Are you a Muslim? Then you have responsibility on you.
Islam is the responsibility of a Muslim, because it is - as we know - not just pronouncing the two testimonies, nor is it worshipping only, rather it is the whole of man's actions. For example, if you enter into the company of faith, you must abide by all its rules and regulations, i.e., you have chosen to be a member of that company freely.
Joining any company requires that each and every member must abide by the laws of that particular company known to full members; if not, then, you are as if a blindfolded member. You must also accept the oneness of Allah; this will make you refrain from any form of associating Allah with anything or anyone.
And you must bear witness to the prophethood of the (s.a.w.), this will make you obey, trust and follow all that he brought from His Lord (It is not fitting for a believer, men or women, when a matter has been decided by Allah and His Apostle, to have any option about their decision) (Holy Qur'an: 33:36).
And you must pray because your prayer restrains you from shameful and evil deeds, and you must fast, because your fasting calls upon refraining from prohibited things both material and spiritual. Based on this, we can see that there are some acts that remove a Muslim from the Muslim family or from the company of faith because he didn't abide by the laws of the faith.
