Wa `alaykum as-Salamu wa Rahmatullahi wa Barakatuh.
In the Name of Allah, Most Gracious, Most Merciful.
All praise and thanks are due to Allah, and peace and blessings be upon His Messenger.
Dear sister, thank you for trusting us and for your question. It is good of you to seek solutions for your problems in the teachings of Islam.
As for your query, you should not hang all your sufferings on envy (what you call nazhar). However, you should do your duties asking Allah Almighty to protect you and your husband from all evils.
Responding to you question, Dr. Mohammad Qatanani, Professor in the Islamic American University and Imam of the Islamic Centre of Passaic County in New Jersey, stated,
Facing different kinds of hardships and difficulties in our life within ourselves and beloved ones is very normal. We are tested in this life. All the affairs of the believer are always good for him.
Allah said in the Quran, “And if Allah should touch you with adversity, there is no remover of it except Him; and if He intends for you good, then there is no repeller of His bounty. He causes it to reach whom He wills of His servants. And He is the Forgiving, the Merciful.” (Yunus 10:107)
Abu Yahya Suhaib ibn Sinan (may Allah be pleased with him) reported that the Prophet (peace and blessings be upon him) said, “How wonderful is the case of a believer; there is good for him in everything and this applies only to a believer. If prosperity attends him, he expresses gratitude to Allah and that is good for him; and if adversity befalls him, he endures it patiently and that is better for him.” (Muslim)
When hardships and difficulties happen, they may be because of envy “hasad” or any other reason. It is very important to ask medical doctors and certified counselors to learn about your situation. Don’t hang everything on the envy and magic (sihr).
Regardless of any situation, I urge you and your husband to recite the Qur’an every day and the adhkar (daily supplications) in the morning and the evening. It is the best for protection and heeling. Be strong by believing in Allah, His decree, relying on Him.
Allah Almighty says, “But they injure thereby no-one save by Allah’s leave. And they learn that which harmed them and profited them not. And surely they do know that he who trafficked therein will have no (happy) portion in the Hereafter; and surely evil is the price for which they sell their souls, if they but knew.” (Al-Baqarah 2:102)
He Almighty also says, “And whosoever kept his duty to Allah, Allah will appoint a way out for him, and will provide for him from (a quarter) whence he has no expectation. And whosoever put his trust in Allah, He will suffice him. Lo! Allah brings His command to pass. Allah had set a measure for all things.” (At-Talaq 65:2-3)
Allah Almighty knows best.
