Believing that the Jinnaat have control and can influence sustenance

Q: Many of us believe in the black magic/evil practices & Jins' effects. Is it valid or is it possible by its means; spoiling someone's Business or Families, subjecting someone to illness etc. Shall one consider some Maulana/Peers who cure the magic on daily routine, or depend on Allah only; as some has told me to consult such Peer because for going for a cure is Sunnat.

Working for a company whose name has Greek religious connotations

Q: A company that was founded and currently owned by a Muslim has the name 'Hyperion.' In Greek mythology, 'Hyperion' is the name of a child between the Sky and Earth deities. This is a formal definition of the word 'Hyperion': "Hyperion is a Titan and a son of Uranus and Gaia. He is married to his sister Theia and has three children - Helios, Selene and Eos. The name Hyperion means "he who goes before the sun" and may have arisen because he was sometimes thought of as the sun." ["Hyperion." Encyclopedia Mythica. 2015. Encyclopedia Mythica Online.] Hence, the name of this Muslim-owned company has the same kufr-shirk connotations as Nike. Please advise:

(1) Is it permissible to utilize the services of a company with such a name? They provide online courses in computer programming and similar services.

(2) Is it permissible to be employed in such a company?

Talaaq via email

Q: A week ago my wife and I were having a huge fight over email. With anger I emailed her the following but had no intention of even stating talaaq. Insha Allah you can provide me with the best explanation. “You said the only way you can have your life back is by me giving you your talaaqs then you got it”. Mufti this is what was said and I did not intend or mean it, I was really angry with previous messages I received from he. I would like your feedback as soon as possible.

Thinking about the poor and needy

Q: I personally feel so guilty when I eat good foods and wear good clothes and live according to my comforts when I see those African kids dying of hunger and thirst. Will Allah Ta'ala ask us about them? What should be our policy in this matter? I mean can we eat and wear what Allah Ta'ala has given us or we should live very zaahidana life and feed those hungry people? I can't be peaceful and eat and drink when I see those hungry people who are near to death but how can I feed them all. Please mufti saheb advise me in this regard what should be the stance that I should adopt. Has Allah Ta'ala made lot of people struck in poverty to test people those who are well off?

Promising to give something to someone

Q:

1. If I told someone that I will give you this dress, that person didn't say anything, can I change my decision and keep the dress for myself?

2. I told a person that I will give you something but that person said he does not need it, but I insisted on him to accept the offer and he somehow agreed, then later I thought in my mind that maybe that person really don't need my thing so well I will give it to some other person then, so can I change my decision like this?

Doubts and waswasas regarding purity

Q:

(A) I had a shower at night. I washed my slippers and feet whilst in the shower.

(B) Then I went out of the house for just over 2 hours wearing the same slippers. When I returned home it is most likely that, by that time, my slippers were dry.

(C) I then got in to the sleeping bag, which I have borrowed from my parents home and which I am using at my house. At the time I went to sleep in the sleeping bag it is most likely that my feet were dry. At the time of sleeping, I thought to myself, when I wake up in the morning I must wash my feet and slippers again as a precautionary measure.
