﴾88﴿ And eat of what Allah the Exalted has given you, lawful for you, and fear Allah the Exalted in whom you believe
﴾89﴿ Allah Almighty does not blame you for your unwilling oaths, but He blames you for taking oaths, So the expiation is to give food to ten poor people from the middle of the food you eat, your family or their clothes or freeing slaves, So whoever cannot do it, then it is on him to fast for three days (one by one) this is the expiation of your oaths and when you swear, And keep your oaths, also Allah the Exalted declares to you His decrees that you should be grateful

[88] In this, there is emphasis on "do not forbid," and the conditions of consumption are mentioned—that it must be lawful and pure.
The purpose of "eat" is to benefit from what is lawful in terms of food, drink, clothing, riding, and other things.
Since eating is the main objective, it is mentioned specifically.
"Lawful and pure": Lawful is that for which there is no legal evidence of prohibition, and pure is that which is also free from doubt.
It is narrated from Ibn al-Mubarak that lawful is what is obtained through lawful means, and pure is what has nutritional value, supports the body's development, and is not harmful to health.
[89] The connection of the verse is that Qurtubi and Sam'ani have narrated that those noble Companions who intended monasticism had taken oaths upon it.
Then, when the verse was revealed: "Do not forbid the good things which Allah has made lawful for you," they asked, “We have taken an oath, so what is the ruling?”
Then this verse was revealed: "Allah does not hold you accountable..." similar to verse 225 of Surah Al-Baqarah.
Accountability is of two types: first, worldly—meaning expiation, and second, of the Hereafter—meaning the punishment of Allah.
Here, both types of accountability are negated.
"Regarding unintentional oaths": originally, "laghw" refers to something discarded without care. Laghw is of two types:
First, uttering words of oath from the mouth out of habit without intention—like some people say habitually, "By Allah," "I swear."
The second type is swearing about a past action in denial—saying they did or didn’t do something, while in reality they forgot.
The first is the opinion of Imam Shafi’i (may Allah have mercy on him), and the second is the opinion of Imam Abu Hanifa and Imam Ahmad (may Allah have mercy on them).
The preferred opinion is that both are included in unintentional oaths.
"That which you bind with oaths": the original meaning of "aqd" is to bind, so here it refers to an oath tied to a future action or inaction, and this is called a binding oath.
Breaking it requires expiation by consensus—meaning "by violating what you bound" or "if you break it."
"So its expiation": this explains "He holds you accountable," and it is called expiation because through it, the sin of breaking the oath is concealed and forgiven.
