I want to engage in temporary marriage with a woman where I will be her agent to pronounce the marriage formula as well as my own. What is the correct formula I need to pronounce on her behalf?
If she wanted you to recite on her behalf and both of you agree the period (Muddah) of marriage and the (Mahr), you say: ZAWWAJTU MOWAKKILATI (her name) LINAFSI 'ALAL MAHR AL-MA'LOOM LIL MUDDATIL MA'LOOMAH. Then say immediately: QABILTU ATTAZWEEJA LINAFSI 'ALAL MAHRIL MA'LOOM LIL MUDDATIL MA'LOOMAH.
If your Arabic is not proper, you should seek help from a person who can pronounce a Arabic properly.
If she is from People of Book (Ahlul Kitab non Muslims) and you have already a Muslim wife in permanent marriage, you need the permission of your Muslim wife before engaging in temporary marriage with a woman from Ahlul Kitab ( Christian , Jewish, Zaorastrians).
Wassalam.
