For Marriage
Do not be deceived by appearances; it is not a suitable marriage for you at all. Abandon it.
For Business / Deal
Although it appears to be a good deal outwardly, it is not so, and you will suffer a loss.
يَا أَهْلَ الْكِتَابِ لَا تَغْلُوا فِي دِينِكُمْ وَلَا تَقُولُوا عَلَى اللَّهِ إِلَّا الْحَقَّ ۚ إِنَّمَا الْمَسِيحُ عِيسَى ابْنُ مَرْيَمَ رَسُولُ اللَّهِ وَكَلِمَتُهُ أَلْقَاهَا إِلَىٰ مَرْيَمَ وَرُوحٌ مِّنْهُ ۖ فَآمِنُوا بِاللَّهِ وَرُسُلِهِ ۖ وَلَا تَقُولُوا ثَلَاثَةٌ ۚ انتَهُوا خَيْرًا لَّكُمْ ۚ إِنَّمَا اللَّهُ إِلَٰهٌ وَاحِدٌ ۖ سُبْحَانَهُ أَن يَكُونَ لَهُ وَلَدٌ ۘ لَّهُ مَا فِي السَّمَاوَاتِ وَمَا فِي الْأَرْضِ ۗ وَكَفَىٰ بِاللَّهِ وَكِيلًا

O People of the Book! Commit no excesses in your religion: Nor say of Allah aught but the truth. Christ Jesus the son of Mary was (no more than) a messenger of Allah, and His Word, which He bestowed on Mary, and a spirit proceeding from Him: so believe in Allah and His messengers. Say not "Trinity": desist: it will be better for you: for Allah is one Allah: Glory be to Him: (far exalted is He) above having a son. To Him belong all things in the heavens and on earth. And enough is Allah as a Disposer of affairs.
