There is no specific Surah in the Quran that is designated for a normal delivery. The Quran is a guide for all aspects of life, including health and well-being, but it does not prescribe specific verses for medical procedures.
It's important to consult with qualified medical professionals for advice and guidance regarding pregnancy and childbirth. The Quran emphasizes seeking knowledge and understanding, and medical professionals are the best source for information related to these matters.
