The benefits of the verse: ((And how can you take it back when one of you has entered into the other, and they have taken from you a solemn covenant?))

Among its benefits is that it is a mark of eloquence for a speaker to present the ugliest image to deter people from what he wishes to deter them from, as indicated by His saying: The contract implies that with this entry, each of the contracting parties returns to what they were before; the woman returns with her mahr, and the husband has received his compensation, which is the permissibility of her private parts. Among its benefits is the reference to the secret between the husband and wife, as indicated by His saying: This entry is a known entry, a well-known entry. Therefore, the one who reveals the secret between himself and his wife is among the worst of people in rank on the Day of Resurrection in the sight of Allah. Among its benefits is that contracts are covenants, as indicated by His saying: There is no doubt that contracts are covenants. Accordingly, fulfilling the covenant falls under the meaning of Allah’s saying: and under His saying: Does fulfilling contracts refer only to fulfilling the essence of the contract, or to its essence and the conditions and attributes added to it? It is the latter, because the conditions stipulated in contracts are among the attributes of the contracts. Therefore, if the essence is fulfilled, the attribute must also be fulfilled. Based on this, it follows that the verse indicates the obligation of adhering to the conditions in contracts, except for what the Shari'ah has prohibited. If the Shari'ah prohibits a condition, it is forbidden to stipulate it and forbidden to fulfill it. For example, if a seller stipulates to the buyer that he must have the loyalty (wala') of the slave he sold him, this is an invalid condition that is not valid; the Prophet (peace and blessings be upon him) publicly invalidated it. Similarly, if a seller stipulates to the buyer of a female slave that he must have intercourse with her for a month, this condition is invalid. Why? Because when he sold her, ownership transferred to the buyer, so if the seller had intercourse with her (if he had stipulated it), she would not be his property, and his intercourse with her would be zina. If the seller of the female slave stipulates that she serve him for a month, for example, there is no harm in that, because service is permissible from a right-hand possession and from others. Among its benefits is the gravity of the marriage contract and that it is a contract that must be given attention, as indicated by His saying: This is also indicated by Allah’s saying regarding divorce: meaning, control it. Control it with what? With counting. But why did He not say "with counting"? Because it was their custom to control things with pebbles; when the people came, they would take pebbles equal to their number for the sake of control. Accordingly, the poet said:
I am not the most numerous of them in pebbles, but honor belongs to the one who is most numerous
How can one be more numerous than pebbles? Is there a benefit in the multitude of pebbles? Yes, the pebbles by which the number of a tribe is known, if it is large, have a benefit. Therefore, he said, "but honor belongs to the one who is most numerous," meaning that no one else is more numerous or surpasses him in number. So we say that this noble verse indicates the danger and importance of the marriage contract, and that it must be cared for, preserved, along with its conditions and everything required in it, so that no problem arises between the man and his wife, and so that matters do not occur that have bad consequences.
