Man

Human dignity of woman does not allow her to be with more than man at the same time. It is not only in Islam, but in all main religions that woman is allowed to marry one man at the same time. More than one man at the same time means destroying the dignity of the woman and shaking her self respect. Obviously, if a woman is allowed to marry more than one man at the same time, the society will lose trust in the belonging of the children to their father as no one will know who is the real father of the child. That itself is a big damage to the human sonciety.

Yes as far as they are Muslims.
Muslim sinner , no matter what type of sins, inherits from his Muslim parents. Non Muslim is not allowed to inherit from Muslim.

Wassalam..

Muslim woman is not allowed to marry non Muslim man under any circumstance until and unless he becomes a Muslim.

 We are allowed to pray to Allah for non Muslim to be guided and to see and follow the true religion of Islam.

Sending your topless images of videos to men is allowed because you are a man like them but don't send it to women.

We have authentic narrations in Shia and Sunni books from the Prophet Muhammad (SAWA) stating that wearing gold is not allowed for men as well as wearing pure silk. Regarding gold we have an authentic Hadeeth from Ali ibn Jafar from his brother Imam Musa ibn Jafar (AS) when he was asked: Is it allowed for man to wear gold? He replied: No, because the Prophet (SAWA) did not allow it. ( Wasaa'il al-Shia, V.4, P.415). We have also a narration from Ammar ibn Moosa  from Imam Jafar Al-Sadiq (AS): man should never wear nor pray with gold. (Wasaa'il al-Shia , V4, P. 413).

In Sunni books, Tirmithi and Ibn Hanbal and many others  narrated that the Prophet (SAWA) said: Silk and gold are forbidden on the men of my Ummah, permissible for their women.

That is why it is unanimous among Muslim scholars from all Muslim sects that wearing gold ands silk is forbidden for Muslim men.

Wassalam.

Yes it is permissible.

First of all, we as Muslims believe that Allah is The All Knowing, Most Wise, Most Merciful and we believe that everything comes from Him is based on full wisdom for our interest, that is why we never question His Wisdom in any matter. We believe that the full reason is best known by Allah (SWT), the Messenger (SAWA) and Ahlul Bayt (AS) who are the real successors of the Prophet (SAWA).

We also believe that our human abilities of thinking are limited and can never reach to everything. We know for sure that every order from Allah (SWT) is based on our benefit and we don't question the details.

Hijab is obligatory on females because Allah (SWT) who created males and females made males more attracted to females than females to males in usual situations. Hair of man can be attractive to some females in some situations but females are in general are much more attractive to males. This can be one of the reasons. Men are responsible to work hard to earn livelihood for their families. Hijab of women is for maintaining her dignity, modesty, safety and honour. Hijab also provide safe atmosphere away from sinful acts. Allah (SWT) says in Quran about Hijab on women (So that they are known so that they should not be harmed ( كي يُعرَفنَ فلا يؤذَين)) 33:59).

Wassalam.

Removing such hair and hair on the pubes and under arms is required because it helps keeping the body clean, tidy and hygienic. Such unwanted hair should be removed at least once in maximum of forty days. Leaving it more than forty days in disliked (Makrouh). Leaving unwanted hair for longer period might cause harm for health because of dirt which can accumulate on it and can also disrupt cleaning the area.

'Wassalam.
