What is the ruling on purchasing forbidden things with lawful money and using them for forbidden purposes, and does that affect the acceptance of supplications and good deeds? And what is the ruling on extravagance in buying sweets and fatty foods, and is it considered forbidden food? And does purchasing anything without the father's knowledge make it forbidden food or unlawful money, even though the money is lawful? And what is meant by the Hadith "eating haram," and does it mean the absolute non-acceptance of supplications and good deeds?

The fear of an intelligent person from God's wrath should be greater than their fear of their supplication not being answered. It is not permissible to engage in sins or purchase forbidden things, even if with lawful money or with the father's permission. There is no harm in purchasing permissible things, but purchasing them for a forbidden party is not allowed. Extravagance in food is a bad habit and is reprehensible in Islamic law. A mature, discerning son has the freedom to dispose of his money as long as it does not violate Islamic law or affect the maintenance of his parents, but filial piety requires obeying them in what is right. The meaning of the Prophet's (peace be upon him) saying, "How can he be answered?" is to preclude an answer for someone with such characteristics, but God might answer him out of grace or as a gradual enticement (istidraj). The acceptance of a disobedient person's worship is known only to God, and the greatest cause for the acceptance of obedience is piety.
