Firstly let me describe about wazifa that what is wazifa? Wazifa is a kind of pray or dua that means you are asking help from Allah. It is gonna haram if you are not praying to Allah and asking help from others rather than Allah. Once we said wazifa that is specifically means that we are praying Allah for need of help for some kind of specific problem.
Secondly, question is wazifa for love marriage is haram. so I can say no because marriage (Nikha) is a halal deed and doing wazifa for halal thing is halal. I can say wazifa is better than magaic. wazifa may take time to show some results not instant as magic but still better for peace of mind that you are doing something under the circle of islam.
Furthermore, if your intentions are wrong and do not want to do Nikha. Then it is haram to having relationship with non Mahrem.
thank you akhtar bhai for clarification I also had the same issue about fluff there are a lot of confusions because of online has bundle of stuff. We even do not know that which one is correct or which one is going to work for us or not or even sometimes they have not mentioned any details about wazifa just write wazifa and that is it. I found this platform useful for me. You are really helping people with there problems. Akhtar bhai you are the best keep it up.
