Can you have human/animal figure drawn into your mehndi design? Does it cause any issues for praying due to drawing of a figure temporarily inked into the skin?

It’s makrooh in namaz

I want to know if we can pray in front of window, cupboard or Bed ?

It’s ok

If we are in our menstruation period can we go inside Imam Ali (As) shrine and watch his grave without touching it ?

To stay or halt in all other Masjids, and similarly, on the basis of obligatory precaution, to stay in the shrines of the holy Imams. However, there is no harm if one crosses or traverses through a mosque, entering from one gate and exiting from another.

What amaal can i do to meet Imam Mahdi aj.Either in my dreams or in person.

Imam (a) meets people who are pure in their heart, sincere in devotion and are humble in the path of Allah (swt). It does not necessarily involve Amaal or to be a scholar etc

But it is highly recommended to keep praying to Allah for the blessed meeting and not to give up. Sometimes we meet him in person or In dream but we don’t recognise him.

Dua Ahad every morning for at least 40 morning
2 Rokah after fajr and gift it to Imam (as)
Give Sadaqa on behalf of Imam
Improve Akhlaq and relationship with Allah

Could you recommend an amaal I can do at home to meet Imam Mahdi either in person or in my dreams?

There is no authentic Amal for that.

Can you recommend an amaal to recite to help meet Imam Mahdi aj?

You may read dua e Ahad for 40 days after namaz e Fajr In’Sha’Allah you will meet Imam Zamana as Imam Jafar Sadiq A’s has promised.

And what about the days in which I may miss fajr due to menstruation?

Continue after the taharat.

Is it haram or makrooh sleeping on your stomach

It’s makrooh

I am a nationality(removed) Syed woman from both sides, maternal and paternal. My sister is in love with a (removed) boy. They were studying together in the same university.
From what I know they are strict (removed). My sister wants to marry this (removed) boy but my family, especially I am very much against this.
Please advise me on how to convince her to stop talking to him, and also please tell me any dua or Quran surah which I can recite to change my sisters mind and heart from marrying. Please also tell me some points which I can tell her to change her mind like how difficult it is for a shia Syed woman to marry outside of sect.

For that problem do this amal:
Read each surahs 14 times a day
Saturday surah Fatah
Sunday yaseen
Monday waqiyah
Tuesday Rahman
Wednesday Jin
Thursday mulk
Friday surah sajda

For how many days I have to do this amaal?

Only one week.
