I bought a bicycle in one of the years for (130 pounds), and after seven years of using it, its value decreased entirely; it became old when selling it

The questioner : He says that he bought a bicycle in one of the years for the sum of one hundred and thirty pounds. And in these days, after the passage of seven years in using it, where its value decreases as it becomes old if you want to sell it, except that a person raised the value of this bicycle by the sum of one thousand two hundred pounds, an increase of one thousand seven hundred. What is the ruling on this large increase, since the hadith says: "salt for salt, barley for barley, and dates for dates, like for like, and whatever is increased is riba"? Please inform us, may Allah reward you?

The Shaykh : Repeat the question, did I understand?

The questioner : He says that he bought a bicycle in one of the years for the sum of one hundred and thirty pounds.

The Shaykh : Very well.

The questioner : And in these days, after the passage of seven years in using it, where its value decreases as it becomes old if you want to sell it, except that a person raised its value...

The Shaykh : Which person?

The questioner : Another person.

The Shaykh : Yes.

The questioner : He bought it from him for the sum of one thousand two hundred, an increase of one thousand seven hundred. What is the ruling on this large increase? He says after use?

The Shaykh : Yes. This increase is not a problem if that is due to the rise in the value of these bicycles.

The questioner : Yes.

The Shaykh : Because there is a difference between the value of things seven years ago and their value today. However, if this increase is because the buyer is ignorant of the price and you deceived him and sold it to him for this amount, although it is not worth it, then this is forbidden for you, because it is not permissible to deceive any of the Muslims, by the saying of the Prophet (peace and blessings be upon him): .
And prices often rise in less than this period. Sometimes a person buys a thing for one hundred, and within one year it rises to one thousand or more, so there is no blame on you if you sold it with the increase.
And as for your saying: that this may be riba, because the Prophet (peace and blessings be upon him) said: , this does not fall under this hadith that you mentioned, because this hadith is intended for when each of these things is sold for its kind, such as if I sell gold for gold, then there must be equality and exchange in the place of the contract, or if I sell silver for silver, then there must be equality and exchange in the place of the contract, or if I sell dates for dates, then there must be equality and exchange in the place of the contract. But if a kind is sold for another kind, such as if I sell dates for wheat, there is no problem with the increase, but on the condition that it is hand to hand, by the saying of the Prophet (peace and blessings be upon him): .
