For Marriage
Do not do it under any circumstances. Repent (Tawbah) for your sins and get this thought out of your head.
For Business / Deal
Do not do it at all, as you will deeply regret it later.
وَلَنُذِيقَنَّهُم مِّنَ الْعَذَابِ الْأَدْنَىٰ دُونَ الْعَذَابِ الْأَكْبَرِ لَعَلَّهُمْ يَرْجِعُونَ
Walanutheeqannahum mina alAAathabi aladna doona alAAathabi alakbari laAAallahum yarjiAAoona
And indeed We will make them taste of the Penalty of this (life) prior to the supreme Penalty, in order that they may (repent and) return.
