Authenticity of a Durood

Q: Is the following Durood and virtue authentic?

اَللّهُمَّ صَلِّ عَلَى سَيِّدِنَا مُحَمَّدٍ مَّا اخْتَلَفَ الْمَلوَان وَتَعَاقَبَ الْعَصَرَانِ وَكَرَّ الْجَدِيدَانِ وَاسْتَقْبَلَ الْفَرْقَدَانِ وَبَلِغْ رُوحَهٌ وَأَرْوَاحَ أَهْلِ بَيْتِهِ مِنَّا التَّحِيَّةَ وَالسَّلَامَ وَبَارِكُ وَسَلِمُ عَلَيْهِ كَثِيرًا

Whoever recites this Durood Shareef three times in the morning and three times at night will get the thawaab of reciting Durood Shareef thirty thousand times in the morning and thirty thousand times at night.

Joining a second jamaat in the masjid

Q: As you are aware, in Gulf countries, in the Masjid after the main congregation is over, there are many second and third small congregation/jamaat prayers going on in the masjid with 5 people or 6 people or 10 people ,and so forth. As far as I know, in Hanafi Fiqh, it is not considered okay to make second jamaat in the masjid. As a Hanafi, what should a tourist visiting a Gulf country or a resident of a Gulf country do if he misses the main congregation and he sees the second smaller congregations of a handful people going on? Should he join it or should he pray the fardh separately?

Hanafi performing Asr Salaah in Shaafi'ee time

Q: As the Asr prayer for the Ahnaaf starts after Mithle-Thaani, in Gulf countries it starts at Mithle-Awwal and the jamaat of Asr in the Masjid is made whilst the Dhuhr time of Ahnaaf is still going on and since in each and every part of the Gulf the asr jamaat is at earlier times, what should a person do? Should he join the jamaat or should he pray alone for Asr prayer? 

A wifes primary duty is her husband and children

Q: I am currently taking care of my parents who live in the unit next to me in a complex. My father wants me to buy a house so that I can accommodate the two of them (parents want to buy the house for me) but they do not want my husband to stay with us (they can't get along) and don't want my married children or grandchildren to visit on a regular basis. I cannot live without my husband and children. My parents want me exclusively to take care of them.

I'm the daughter and I have 3 brothers who don't want to take care of them because of previous issues with their wives. I do not mind living the way I'm living in a rented place because I have my own space and they have their own space.

Am I suppose to be listening to my parents or does my own family (husband) take priority. What is the Islamic view? 

Meaning of shahaadah

Q:

1. Some say that actually saying the shahaadah is not required to be considered a Muslim and rather just to actually believe in your heart while others say that you have to actually say the shahaadah, which is correct?

2. Why does the Hanafi madhab believe that despite not praying, as long as they believe in the shahaadah's message, people can still be considered Muslim and eventually enter paradise. If it is said that the Prophet (sallallahu alaihi wasallam)'s uncle believed that his nephew was not lying and telling the truth yet will enter hell? Is it because he refused to say the shahaadah, regardless of whats in his heart?
