Is it permissible to carry a small Mus'haf during supererogatory and obligatory prayers for one who forgets some verses, and what is the supplication for obtaining a righteous spouse? And does reciting Al-Fatihah 112 times open closed doors? And what are the supplications that should be recited to relieve worries? And is the death of a father from a stroke in the brain and heart considered martyrdom? And what should I do regarding a young man who is my brother's friend, and I pray to Allah that he be destined for me?

May Allah relieve your distress and grant you a righteous spouse. Here are the answers to your questions:

1. There is no specific supplication for marriage; rather, supplicate for the good of this world and the hereafter.

2. Delayed marriage may be a trial or for divine wisdom, and not necessarily due to an evil eye or envy. You should perform ruqyah (definition) if you strongly suspect their presence.

3. Continue to supplicate and remember Allah to comfort yourself in the face of calamities.

4. Ascertain the young man's situation before proposing marriage to him, and seek help from trustworthy individuals or one of your friends.

5. We do not know of any evidence that reading Al-Fatihah 112 times opens closed doors. Reading with a specific number without sharia (definition) evidence is considered an innovation.

6. The hijab (definition) is an obligatory religious duty for women.

7. Crying over the deceased without wailing is permissible, and women visiting graves is permissible under certain conditions.

8. The "mabṭūn" (one who dies of an internal illness) is a martyr, and this does not include someone who dies of a stroke. Calamities expiate sins.

9. A Muslim comforts themselves during calamities by remembering the calamity of the Prophet's death, peace and blessings be upon him, for it is the greatest of calamities.
