Second wife forfeiting her right for her husband to spend every second night with her and reclaiming it

Q: I have taken a second wife - but before I had married her we had an agreement in place that I will not stay every second night with her. Now she is demanding that right. She is a revert. She said that she didn’t know how hard it was going to be a second wife. She knew from the beginning the Islamic laws of 2nd wife.

Is she valid in her argument and can she change her mind and do I have to now fulfill her right?

Some heirs giving their shares of the inheritance to other heirs

Q: My wife has passed away. Her heirs to her inheritance are: I (Her husband), three daughters (who are in S.A). Other heirs are: her brother and sister who are in India.When I told them about their share of inheritance and asked for their banking details they insist that I should give their shares to my three daughters. Is this permissable?

Forcing people to wear the mask

Q: There is a view amongst some Muslim Scholars during this Covid Pandemic that one should have Tawakkul and ignore the government protocol and recommendations. Even our children in Madrasah are being told to remove their masks, while their schools insist on masks being worn.

Did our Nabi Muhammad (sallallahu alaihi wasallam) and his noble Sahabah (radhiyallahu anhum) not wear body armour for protection in preparation for wars? In doing so, did they not have Tawakkul? If these were worn to offer some protection why is our wearing masks and exercising social distancing viewed by some as having no faith in Allah Ta'ala?

The statistics speak for themselves - Muslims make up around 2% of the South African population but account on some days for close up to 30% of the fatalities countrywide. Should the Ulama not be cognizant of this and guide the community accordingly?
