Q: Should the dried pus on a pimple be removed during wudhu and ghusal?

Q: I got a procedure of IUCD for contraception on July 1, 2019. It was important as per doctors instruction due to some medicines with which I cannot conceive at the moment. The gynaecologist said that in the start I will face some extra/heavy bleeding or irregular spotting due to this.

My previous routine of periods was 8 days except for Ramadhaan i.e. 9 days. My old dates for 2019 were

17 Jan - 25 Jan
12 Feb - 20 Feb
11 March - 19 March
7 April - 15 April
2 May - 11 May
30 May - 7 June
Important one (25 June - 5 July)

My questions are:

1. I took a bath after 10 days completion in my last cycle i.e 25 June to 5 July due to spotting as maximum days for periods are 10 days but still I got spotting for 3 more days. I offered my salaah and Quran. Was this calculation ok?

2. I started spotting again on 16 July but as per my last cycle, there wasn't a gap of 15 days in between two cycles. I am still having light spotting plus bleeding. I am offering salaah and Quraan with fresh wudhu everytime. Am I correct?

3. If in the last cycle I consider it to be 8 days then 25 June - 3 July then after 18 days of habit I must be having periods on 21 July, so what should I do? How would I calculate that either its istihaaza or periods? 

Q: My wife cheated on me twice. The first time I caught her was when my son was 1 year old and second time I caught her my son was 4 years old. She likes my sisters husband. What should I do?

Q: While sitting in attahiyyat, if I lift my hand from my thigh, does this affect my prayer?

Q:

1. If I came up from first sajdah without keeping my hand on my thigh and then go for the 2nd sajdah, does this affect my prayer?

2. If my knee raised a little after my first sajda, does this affect my prayer?

Q: I came to know by one of the dawat-o-tabligh elders that we can make intention of many different namazes (e.g: if we are praying ishraq then we can make intention of tahiyaatul wudhu, tahiyyatul masjid, salaatul hajat, salaatul taubah, etc.)

1. Is it true?

2. How many total extra niyyats can we make for a two rakat nafil?

3. Can we do the same for zohar, maghrib and isha nafl prayers?

Q: Kal mene thora jazbat me Quran pak pe hath rakh ke ek jhoot boldiya to mujhe ye pochna he ke me ab kiya karu?

Q: Can we name a baby boy Mikaeel?

Q: While grinding, I grinded a short hair like that of an eyebrow with the food, can I eat this grinded food?

Q: My husband insists that my 9 year old son cannot offer salaah in loose shorts which are below the knee. He insists upon trousers quite recklessly and even makes him wear a thobe on top of his T-shirt and shorts. I am concerned that he is overcomplicating simple guidelines on which he can create lots of confusion in a developing childs brain.

Isn't this an innovation? It's not a precaution, but more of an obsession as people all over the world offer salaah in loose shorts below the knee.
