Bismillāh al-Raḥmān al-Raḥīm

Thank you for your question. As long as there is no stipulation in the marriage contract to the contrary a man is entitled to up to four permanent wives in Islamic law and that is not contingent on the approval of any of his wives.

It is of course wise to seek approval from any current wives, but that is not a condition for the validity of another marriage contract and not having the approval of a previous wife would not mean that the following marriage was sinful in any way.

May you always be successful. 

There are different ways of explaining the concept of the soul. You may want to search for the article 'Explanation of Soul or Self in the Holy Qur'an and Atman in the Ancient Upanishads' by Dr. Ali Reza Khajegir and Mohammad Reza Afroogh, in the Journal of Religion and Theology, Vol. 2, SRYAHWAR Publications.

Also, see the work by Ayatullah Ibrahim Amini on the Ma'ad in the Qur'an on this website.

The Prophets of God were divinely appointed and tasked with bringing people to the path of righteousness, honesty and integrity.  They were not known to be manipualtive or believe that the end justifies the means as is common in politics.

A good example is that of Prophet Yusuf (a) who suffered from the consequences of the cunning conduct of some women of Egypt.

So when he saw that his shirt was torn from behind, he said, ‘This is [a case] of you women’s guile! Your guile is indeed great! (Surah Yusuf, Verse 28)

The Hajj is the annual pilgrimage to the house of God in Makka. It is obligatory for every Muslim to perform, once in their lifetime, if they have the means to do so. It ca only be performed at a specific time in th eyear.

The Umrah is a recommended visitation to the house of God and can be performed around the year except at the time specifically reserved for Hajj.
