You can perform this Bismillah Wazifa for love after Isha Namaz. It does not have to be done immediately after Isha, but it must be performed sometime after Isha and before sleep. You must be in a state of Wudu while reciting the Bismillah Wazifa.
Recite the following:
فلاّن كُن فِي الحُبّ مَعِي بحق بِسْمِ اللهِ الرَّحْمٰنِ الرَّحِيْمِ
Fulan, kun fil-hubb ma‘ī bi-haqqi Bismillah hir rahman nir raheem
Replace فلاّن / Fulan with the name of the desired person you wish to fall in love with you. Recite this exactly 786 times every night, not more and not less. You can use a digital counter or a traditional Tasbeeh to keep track of the counting.
InshaAllah, within just a few days, you will see that your desired person will begin to develop strong feelings of love for you, and that person attitude will completely change towards you.
I was in a relationship with him for six months during which he often told me that we will definately get married Inshallah. Now just Recently he has suddenly stopped talking to me. My main intention has always been marriage and I truly love him. I feel like I cannot live without him and I deeply want that he feels the same way and that we can be together. Can you please help me with my situation?
Yes, you can do this Bismillah Wazifa 786 times for love. Once he starts showing love and comes back to you, there is a high chance that he will marry you. But if he comes back and still does not get married, you can contact me, and I will suggest a Wazifa according to that situation.
