3. What other writings does one have to cut off (or just cover) before disposing?

Using the name of Hazrat Khadeejah (radhiyallahu anha) to promote feminism

Q: In regards to the fitna of feminism arising, many our Muslim women have fallen for this wherein if you try to advise them that university and offices is not a place for a Muslim woman, their argument is that Hazrat Khadeejah (radhiyallahu anha) was a businesswoman. My question is: 

I find that using Hazrat Khadeejah (radhiyallahu anha) as an example of why they want to work in the corporate sector saying she was a businesswoman, etc. is very disrespectful towards the mother of the Muslim women. How do I explain to them that using the Sahaabiyyaat as examples is very disrespectful?

Accusing a family member of doing jadoo (black magic) without evidence

Q: A family was going through difficulty and they got in touch with a Moulana who does amaliyaat to check if it's jadoo (black magic). The Moulana aamil blamed Rashid in the family of doing jadoo. 

After hearing this, the family accused Rashid of doing jadoo on the family. They are mentally torturing him, because of this Rashid has gone into depression. Rashid denied the allegations but because the Moulana aamil has blamed him, they are not willing to listen to him or believe him. The family is also gossiping to others about Rashid doing jadoo. 

What is the Islamic ruling regarding the three people; 

1. The Moulana aamil who did istikhara or checked via Jinn then blaming Rashid of jadoo, 
2. The family accusing Rashid of jadoo and 
3. Rashid who is being wrongly accused of doing jadoo?
