Is the exhaustion we experienced after marriage and the delayed pregnancy due to the evil eye, and what should I do?

Patience and abundant supplication are recommended. You have done well by adhering to righteousness, maintaining prayer, reciting Surah Al-Baqarah, and increasing your acts of seeking forgiveness. These deeds help facilitate matters and grant well-being from affliction, as affirmed by the Almighty's saying: "And whoever fears Allah – He will make for him a way out And will provide for him from where he does not expect."

You should first consult doctors. If no physical cause is found, the reason might be an evil eye or sorcery. In this case, you should perform ruqyah (Islamic exorcism). It is preferable for a person to perform ruqyah on themselves. If assistance from others is needed, seek out righteous individuals and beware of charlatans.

Moreover, good deeds and kindness to creation are means of repelling affliction, as the Prophet, peace and blessings be upon him, said: "Acts of kindness protect against evil fates."
