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.
