If I need to recite ziyarat e ashura for 40 days for a specific hajat then what will be the order of the ziyarat, the two rakaat prayer and dua alqama?
I do this amal or just make niyyah of that hajat? And when do you make dua in this whole aamal?

Recite ziyarat and after ask your hajjat.

So you know of any lectures or video or even book really for English speakers that wish to learn Quranic Arabic. I'm specifically looking for something that breaks down the Arabic of ayahs in the Quran and shows how it changes the meaning and how it could be interpreted differently. Anything to help me understand the eloquence of the Qur'an. Also I prefer it be from a Shia

How can we proove the attack on the door of Fatima Zahra (s.a) because it has only one narration chain of Kitab Sulaym ibn Qays. And The sunni brothers call it weak and many shia scholars has doubted it's authenticity. Furthermore, there are narration about threatening to burn the door from other chains but the full incidence is only mention in Kitab Sulaym ibn Qays. Are there any other narration chain of the complete incident. If no, how can we prove?

I want to ask that how to make your mind and soul pure?
How to make your soul and mind to think positively?

Shaytan knows our weak points thus we need to realize what they are as well. Just as a country will prepare its military to defend its weak points we must also prepare our army to defend our weak points against our Shaytan. A very effective dua against the Shaytan is:

‎اللهم إن إبليس عبد من عبيدك يراني من حيث لا أراه وأنت تراه من حيث لا يراك وأنت أقوى على أمره كله وهو لا يقوي على شيء من أمرك, اللهم فأنا أستعين بك عليه يا رب فإن لا طاقة لي به ولا حول ولا قوة لي عليه إلا بك, اللهم إن أرادني فأرده وإن كادني فكده, واكفني شره, وأجعل كيده في نحره برحمتك يا أرحم الراحمين, وصلى الله على محمد وآله الطاهرين.

“O Allah, Iblis (Satan) is one of Your creatures who sees me from a place that I cannot see him and You see him from a place that he cannot see You, and You have power over all his affairs while he does not have power over any of Your affairs. Therefore O Allah, I resort to You for help against him, because O Lord (provider, nourisher, sustainer, the one who transforms potentiality into actuality) I do not have any capability against him, no power to change or force to enact, except through You. O Allah, If he intends evil for me, turn it back on him, and if he schemes against me then you scheme against him. Save me from his evil, and make his scheme to attach to his own neck. By Your mercy, O the most merciful of those who show mercy. May Allah bless Muhammad and his purified progeny.”

When we are on our deathbed we have to say our shahada but I want to know if saying Ya Ali instead is okay or correct because our religion revolve around the ahlulbayt and they hold a big and important role in Islam shiism

It has been recommended by the Prophet and his household (as) to say the shahadatayn on our death beds and then to reaffirm our beliefs and believing in the wilayat is one of our beliefs.

How to create sincerity in worship and how to avoid hypocrisy?

Build up your beliefs by studying about Islam and prepare yourself mentally before salat to realize who you are standing in front of

I find my spirituality changes. one week I am very spiritual while another time I may not be. My lifestyle is the same. Is it related to me because I'm a women? Why do I go through this loss of spirituality while I don't feel like doing any mustahabat at all and just be lazy?

This happens to most people regardless of gender. Ask Allah to help you and strive to get in the habit of reading the benefits of salat and acts of worship.
