For Marriage
You will have a life entirely of hardship and torment. It must be abandoned.
For Business / Deal
It is by no means in your best interest (Salah). If you perform this transaction, you will face many problems and fall into Haram. Abandon it.
وَمَا كَانَ لِمُؤْمِنٍ وَلَا مُؤْمِنَةٍ إِذَا قَضَى اللَّهُ وَرَسُولُهُ أَمْرًا أَن يَكُونَ لَهُمُ الْخِيَرَةُ مِنْ أَمْرِهِمْ ۗ وَمَن يَعْصِ اللَّهَ وَرَسُولَهُ فَقَدْ ضَلَّ ضَلَالًا مُّبِينًا
Wama kana limuminin wala muminatin itha qada Allahu warasooluhu amran an yakoona lahumu alkhiyaratu min amrihim waman yaAAsi Allaha warasoolahu faqad dalla dalalan mubeenan
It is not fitting for a Believer, man or woman, when a matter has been decided by Allah and His Messenger to have any option about their decision: if any one disobeys Allah and His Messenger, he is indeed on a clearly wrong Path.
