Transactions containing a violation of the Shari'ah: Does this result in sin without the earnings being corrupt, or do the earnings become corrupt?

The questioner : A transaction in religion, meaning a transaction that contains a violation of the Shari'ah, such as not being hand-to-hand, and so on. Does this result in the corruption of the earnings, meaning the earnings become corrupt, or does one simply sin and the earnings remain...?

The Shaykh : What results?

The questioner : Does it result in the corruption of the earnings, making the earnings corrupt, meaning this money is forbidden, or does one simply sin and the money is the equivalent of that? For example, I sold you gold, but in a transaction that violated the Shari'ah, it was not hand-to-hand, for example... we violated the texts... and the sale was completed between you and me, and you received the money or the gold, and I received... When we violated the Shari'ah here, did we only sin, or does it result in this earnings being corrupt, the earnings that were obtained?

The Shaykh : What is the difference between saying we sinned...

The questioner : Yes.

The Shaykh : ...and that it is corrupt?

The questioner : The difference is that, for example, this earnings is lawful.

The Shaykh : Did you understand the question?

The questioner : Yes, you want me to distinguish for you, meaning I understood.

The Shaykh : What is the difference between being sinful or his earnings being corrupt?

The questioner : Yes, some of our brothers from the students of knowledge said that if I sold you this gold, the money is lawful, but you sinned because you did not follow...

The Shaykh : Do not deviate from the topic, tell me what is the difference? The one who eats illicitly, does he sin or not?

The questioner : He sins, yes.

The Shaykh : And the one who sinned, did he eat illicitly or not?

The questioner: Yes.

The Shaykh : What is the difference then?

The questioner : No, he is saying here that this money came...

The Shaykh : My brother, leave me to what he is saying, may Allah guide you. I am speaking, I and you now, do not say so-and-so said.

The questioner : Okay, I gave you gold and took money in exchange.

The Shaykh : May Allah guide you, do not give examples. The question is clear. You are distinguishing between sinning or eating illicitly, what is the difference?

The questioner : Either way, both mean the same.

The Shaykh : You are distinguishing.
The student : Mahir.

The Shaykh : In any case, we will suffice with this amount for now and ask Allah (Mighty and Majestic) to teach us what benefits us, and to increase us in knowledge, and to grant us success in acting upon what we have learned.
The student : Send prayers upon the Prophet.

The Shaykh : Remember Allah, remember Allah, there is no god but Allah.
The student : May Allah reward you with good.

The questioner : I am speaking to you.
The student : ... .
