Assalam-U Alikum-Wa-Rehmatullahi-Wa-Barakato Shaikh one of my colleague was reverted from Hinduism to Islam. She’s interested in getting married but the Guy is Hindu and the marriage will be according to Hindu’s rituals because her Family dose not know that she has reverted to Islam and am afraid that she might commit a shirk if its done according to Hindu rituals. The guy keeps Fast for the full month of Ramadan from past few years regardless of being Hindu but he has not said the Shadah(لا إله إلا الله محمد رسول الله (lā ʾilāha ʾillà l-Lāh, Muḥammadun rasūlu l-Lāh)There is no god but Allah, Muhammad is the messenger of Allah. So can they get married and can the perform intercourse to produce offspring or is it haram(Fornication) ZINA if he doesn’t accepts the Islam ? What dose the Islam says about this? Kindly provide me with supplications(Dua’s) and tasbeeh which I can provide to her so that Allah Subahn Wa Tallah guides her to the straight path? JazakAllah

Ask her to convert back into Hinduism,, problem solved,, her parents won know she converted to islam, the guy won have to convert, and their kids won't be Haram,,
