Selling a toy which contains music

Q: We have recently received stock of an Islamic toy which we were unaware had music... The toy has many beneficial learning pages such as duas, surahs, Arabic alphabets, etc. but there is a button which plays nasheeds with musical instruments in the background.

Will it be permissible to sell such a toy? If the toy is sold with a note on how to remove the music and if the customer purchases it and chooses not to remove the music wire, will the seller be sinful?

Taunting a Muslim

Q: What is the significance and the ruling if the sunnah about "loving fellow believers and not taunting them" according to some Ahaadith like this:

Sayyiduna Mu’adh (radiyallahu ‘anhu) narrates that Muhammad (sallallahu ‘alayhi wasallam) said: ‘Whoever taunts a brother (Muslim) with a sin (which the Muslim has committed), will not die until he (the taunter) commits the same sin.’

The first Hadith is recorded by Imam Tirmidhi (rahimahullah) in his Sunan and is classified as sound (hasan). (Sunan Tirmidhi, Hadith: 2505 & Mukhtasarul Maqasidil Hasanah, Hadith: 1057. Also see: Targhib, vol.3 pg.310, Sharhul Ihya, vol.7 pg.504 & Al-Mudawi, Hadith: 3462)

Wife having the right to see her children after divorce

Q:

1. My husband and I have been separated since 25 April 2019. I am currently living with my sister and her family. I left my home because my husband abused me badly, this is not the first time that he had lifted his hands. I stayed in the marriage for 5 years whereby I went through physical and verbal abuse to the extent that I was even scared to ask to go and see my 2 boys from my previous marriage. He has a very bad temper, thinks that my family is influencing me and swears my family. I have been supporting him all these years and still am to keep a roof over his head.

In the last 2 months I have spent time with my boys more than I ever did in the 5 years of being married to my current husband. I would like to know my rights as still being married going to see my children as they live with their father? I know that their father is now a non-mahram to me.

2. My current husband does not want to give me my talaaqs. He is prepared to only give one and take his time with the others. I feel so stuck and torn between my family, my boys and my current husband. I dont know what to do. I want to do the things the proper way.
