What is the ruling on wearing a Quranic amulet during pregnancy to prevent miscarriage?

There is no harm in reciting the Quran with the intention of interceding for the preservation of the fetus or the fulfillment of legitimate needs, because it is a lawful intercession through good deeds. It was narrated in the Hadith: "Recite the Quran and ask Allah through it." This indicates the permissibility of asking for whatever one wishes regarding worldly and otherworldly matters through the Quran, or supplicating after recitation. There is no objection to treating a woman with lawful ruqyah by reciting the Quran and the reported supplications, as this is one of the most effective treatments. However, as for seeking protection by hanging Quranic verses or surahs, the correct view is that it is prohibited.
