For Marriage
It is not a suitable case. Focusing only on appearances distances a person from many [important] matters. Abandon it.
For Business / Deal
It is like a "beautiful but venomous snake"; try not to go near it.
أَفَمَن شَرَحَ اللَّهُ صَدْرَهُ لِلْإِسْلَامِ فَهُوَ عَلَىٰ نُورٍ مِّن رَّبِّهِ ۚ فَوَيْلٌ لِّلْقَاسِيَةِ قُلُوبُهُم مِّن ذِكْرِ اللَّهِ ۚ أُولَٰئِكَ فِي ضَلَالٍ مُّبِينٍ
Afaman sharaha Allahu sadrahu lilislami fahuwa AAala noorin min rabbihi fawaylun lilqasiyati quloobuhum min thikri Allahi olaika fee dalalin mubeenin
Is one whose heart Allah has opened to Islam, so that he has received Enlightenment from Allah, (no better than one hard-hearted)? Woe to those whose hearts are hardened against celebrating the praises of Allah! they are manifestly wandering (in error)!
