My uncle‟s earnings are primarily from selling and repairing televisions and other haraam products.

Answer

Politely and respectfully inform him that due to his haraam income it is not permissible for you to accept his invitation. In all probability he will be offended. His annoyance is of no significance. Of significance are the pleasure and command of Allah Ta'ala.

If you know that poison or faeces has been added to the food, what will be your reaction? You will not be concerned with the offence and annoyance of the person inviting you. You will firmly refuse to eat the contaminated food.

Now understand well, the spiritually contaminated food - contaminated with the haraam income – is worse than physically contaminated food. And, understand well, that the Pleasure and Displeasure of Allah Ta'ala are of greater and prior importance than the pleasure and displeasure of your uncle.

Besides the issue of food acquired with haraam income, one should not consume the food of a debtor even if his food is from halaal money. It is Makrooh to answer the invitation of a debtor. The money which a debtor squanders in feasts, should be incumbently paid to his creditors.
