The ruling on one who utters some phrases of shirk (associating partners with Allah) while forgetful

ً
It has become common among some of the general public or some people that they say some phrases of shirk (associating partners with Allah) and then try to get rid of them by citing the ruling,Meaning: they know the ruling but they keep repeating them,So when you say to him: saying, "It is like this,He says: and by Allah, I forgot,For example: saying a word of shirk when swearing an oath, saying: "By the Prophet, or by the life of the Prophet," these words,So when you clarify it to him, he says to you: and by Allah, I forgot, my brother, but I do not affirm this?"

You know that Allah (Mighty and Majestic) said in His Book: [al-Baqarah:286] If a person has become accustomed to swearing by other than Allah, as is found in many Muslim societies—regrettably—they swear by the Prophet (peace and blessings be upon him). If he has become accustomed to this from childhood, and the people around him all swear by the Prophet, then it is not easy for him to leave it in one day or two days, or in one month or two months,When he says: if he forgot, then Allah has excused him if he was forgetful, and it is not unlikely that he was forgetful; because he has become accustomed to it,So we say: strive to remember that this is forbidden, and not to do it.
