Period of breastfeeding

Q: A hadith states لا رضاغ بعد الفصال

Hidaya mentions that the growth from the milk stops after the child's nutrition is changed. If a child was weaned at 8 months due to a 2nd pregnancy, then the mother gave birth and is feeding the 2nd child, can she feed the first child expressed milk?

The child is already weaned, drinking goats milk in abundance. Mothers milk will definitely be more nutritious, but does the hadith mean that it will be prohibited to feed the child who was previously weaned even though it is less than 2 years old ?

Advertising in the newspaper and on online platforms

Q:

1. Is it permissible to advertise for my business in the newspaper?

2. Is it permissible to advertise for my business on advertising platforms like Gumtree and Junkmail? On such platforms, once a person clicks on my ad, he will not see other people’s ads. However, ads from other websites of all sorts may pop up.

3. Is it permissible to advertise for my business on Instagram? If someone has to come to my Instagram account, he will only be able to see my posts.

On all these three platforms of advertising, pictures of animate objects of all sort appear in other people’s ads. Also, some of the ads which appear are of an impermissible commodity.

Embracing a Haaji

Q: I heard that embracing one another on the two Eid occasions by the ummahs usually not done at other days is not permissible in Islam. If so, could they not permit the embracing of haajis at their arrival.
