For Marriage
Something has been hidden from you; if you knew of its existence, you would never do this. Do not do it.
For Business / Deal
This transaction is coupled with deception and trickery; in anything involving deceit, avoiding it is closer to reward (Thawab). So, do not do it.
وَمَا قَدَرُوا اللَّهَ حَقَّ قَدْرِهِ إِذْ قَالُوا مَا أَنزَلَ اللَّهُ عَلَىٰ بَشَرٍ مِّن شَيْءٍ ۗ قُلْ مَنْ أَنزَلَ الْكِتَابَ الَّذِي جَاءَ بِهِ مُوسَىٰ نُورًا وَهُدًى لِّلنَّاسِ ۖ تَجْعَلُونَهُ قَرَاطِيسَ تُبْدُونَهَا وَتُخْفُونَ كَثِيرًا ۖ وَعُلِّمْتُم مَّا لَمْ تَعْلَمُوا أَنتُمْ وَلَا آبَاؤُكُمْ ۖ قُلِ اللَّهُ ۖ ثُمَّ ذَرْهُمْ فِي خَوْضِهِمْ يَلْعَبُونَ

No just estimate of Allah do they make when they say: "Nothing doth Allah send down to man (by way of revelation)" Say: "Who then sent down the Book which Moses brought?- a light and guidance to man: But ye make it into (separate) sheets for show, while ye conceal much (of its contents): therein were ye taught that which ye knew not- neither ye nor your fathers." Say: "Allah (sent it down)": Then leave them to plunge in vain discourse and trifling.
