For Marriage
Do not do it under any circumstances. The inner reality differs greatly from the appearance. Abandon it.
For Business / Deal
Do not be deceived by the attractive appearance; you will deeply regret it.
وَقَارُونَ وَفِرْعَوْنَ وَهَامَانَ ۖ وَلَقَدْ جَاءَهُم مُّوسَىٰ بِالْبَيِّنَاتِ فَاسْتَكْبَرُوا فِي الْأَرْضِ وَمَا كَانُوا سَابِقِينَ
Waqaroona wafirAAawna wahamana walaqad jaahum moosa bialbayyinati faistakbaroo fee alardi wama kanoo sabiqeena
(Remember also) Qarun, Pharaoh, and Haman: there came to them Moses with Clear Signs, but they behaved with insolence on the earth; yet they could not overreach (Us).
