THERE ARE PEOPLE I KNOW WHO WORK IN ENGLAND IN A RESTAURANT AND ARE PAYED VERY
WELL, BUT WHAT THEY DO IS THEY TELL THE AUTHORITY THAT THEY ARE PAYED LESS SO THAT THEY CAN RECEIVE EXTRA MONEY. THE GOVERNMENT HELPS THOSE WHO ARE ON LOW INCOME. IS THIS HALAL FOR THEM TO LIE AND GET THIS EXTRA MONEY? WHEN ASKED THEY REPLY THAT THE TAX IS QUITE HIGH IN THIS COUNTRY. BUT DOES IT MEAN YOU CAN LIE AND GET EXTRA? PLEASE EXPLAIN.IF IT IS WRONG THEN THE MONEY
IS HARAM? THE DUA IS NOT ACCEPTED? HAJ IS NOT ACCEPTED? PLEASE CAN YOU
EXPLAIN. THANKYOU.

Praise be to Allaah. 

It is not permissible to tell lies; doing so is
haraam. Money which he has taken on this basis is also haraam and he has
no right to it. With regard to his du’aa’, the fact that he is
consuming haraam wealth may be a reason why his du’aa’ is not being
accepted, because of the hadeeth, “Then he mentioned a man who had been
travelling for a long time and was dishevelled and dusty; he stretches out
his hands towards the heavens and says, ‘O Lord, O Lord’, but his food
is haraam, his drink is haraam, his clothing is haraam. He is nourished by
haraam, so how can his du’aa’ be accepted?” (Narrated
by Muslim, 1015).

With
regard to his Hajj, the poet said:

“If
you go for Hajj with money whose origin is haraam,

You
will not have made Hajj, but the camels will have.”

And
Allaah knows best.
