The ruling on falling into errors that one did not intend

Question:
We were a group of friends who gathered to discuss and dialogue about matters of religion and the world. One of the attendees raised a question, asking: Can a Muslim live his life as a Muslim 100% of the time while continuing to coexist and interact with his society, including its positives, negatives, and influences? In other words, if he wants to stay away from everything Allah has forbidden and enjoy everything He has permitted in His Book, as well as act in accordance with the Sunnah of His chosen Prophet (peace and blessings be upon him) by doing what it permits and avoiding what it prohibits?
The answers differed, although everyone answered yes. However, the answers differed regarding the percentages. One group claimed that a person is capable of this, meaning that a person can live as a Muslim 100% of the time. Another group did not agree that a person can live a Muslim life 100% of the time. The perspective of the other group, who did not agree with the 100% figure, was that the strength of society and its influences is multiple, and that there may be many incorrect matters, but society approves of them. This group gave the example of football and people’s attempt to encourage this game, despite its lack of benefit for youth to the extent that if youth trained in horsemanship, swimming, and archery, for example.
Another example is image-making and three-dimensional images. Another example relates to human food, namely the meat the state imports from abroad. And another example is bank interest.
Many other examples were cited. When the discussion became long and extended, we agreed on some points and disagreed on others.
We thought we should send a question to your esteemed magazine, hoping to find a satisfying answer from you?

Answer:
The Muslim is not infallible, and , as stated in that noble hadith. But it is possible for a Muslim to live in a society while preserving his religion according to his capacity, acting in accordance with the saying of Allah (Glorified and Exalted is He) : [Surat al-Taghabun: 16].
And his religion is not blemished by the errors that may occur from him, which he did not intend, or which he thought were permissible based on his ijtihad and the information he had, or by his asking some scholars, who issued a fatwa on the matter that did not conform to the pure Shari'ah.
In summary, it is obligatory for the Muslim to fear Allah as much as he can, to forbid what Allah has forbidden for him, and to exert himself in what Allah has made obligatory for him. And if a slip occurs from him, it is obligatory for him to hasten to sincere repentance.
