For Marriage
It is good. Proceed with Tawakkul (trust) in Allah and by observing Sharia standards. Finalize all your talks beforehand so no problems arise later.
For Business / Deal
Proceed after considering all aspects; then perform it firmly and resolutely, and cast away all fear.
يَا أَيُّهَا الَّذِينَ آمَنُوا قَاتِلُوا الَّذِينَ يَلُونَكُم مِّنَ الْكُفَّارِ وَلْيَجِدُوا فِيكُمْ غِلْظَةً ۚ وَاعْلَمُوا أَنَّ اللَّهَ مَعَ الْمُتَّقِينَ
Ya ayyuha allatheena amanoo qatiloo allatheena yaloonakum mina alkuffari walyajidoo feekum ghilthatan waiAAlamoo anna Allaha maAAa almuttaqeena
O ye who believe! fight the unbelievers who gird you about, and let them find firmness in you: and know that Allah is with those who fear Him.
