The ruling on one who is consumed by the pursuit of this world and whose worship diminishes

Question:
The Shaykh said, may Allah protect you: If a person spends his time and effort in seeking Allah’s pleasure and running after it, and he sees an increase that affects him, causing a decrease in his worship and seeking of knowledge, does he know the weight of the servants?

Answer:
Yes, the one who spends all his time seeking this world and diminishes his deeds for the Hereafter, meaning he does not attend the congregational prayer, he does not attend the congregational prayer, and he does not close his shop at prayer time. He says: I have deputies who answer for me, and I remain in my shop and pray in my shop, and I do not go to the mosque. This person is among the slaves of this world, but he does not become a disbeliever because of it. However, his faith is deficient, his tawhid (the oneness of Allah) is deficient, and he is sinful for abandoning the congregational prayer.
