Nathalie Hoslcher did indeed recite the two sentences of the shahada when she was about to marry Sule. However, guidance had come to her long before she met the comedian who is now her husband.
When she was a guest on Maia Estianty's channel, Maia Al El Dul TV, Nathalie revealed the guidance she received in 2010. She shared how it all started and how she wanted to embrace Islam but was still afraid of her family.
