Trimming less than the required amount of hair to come out of ihraam

Q: Kindly advise what should I do and what's the ruling for the following incident:

My husband was not in ihraam, he then trimmed off a fingertip length of a lock of hair, not the entire bottom of the hair. We thereafter kissed and only realized later on that the entire bottom of the hair needed to be trimmed. Is there any penalty for this?

Blood transfusions and organ transplants

Q: I would like to seek clarification regarding the permissibility of blood transfusions, organ transplants, and related medical procedures in Islam. Specifically, I would appreciate guidance on the following: 

1. What is the ruling on receiving and donating blood? 

2. What is the ruling on organ transplantation in general? 

3. Is there any ijma on the permissibility of organ transplants, as some individuals claim? 

4. Are there differences of opinion regarding organ donation during one’s lifetime versus after death? 

Going for umrah when one has outstanding qadha salaah

Q: Alhamdulillah by the mercy of Allah, I have been consistent with my salaah with Jamaat for many years, and have no qadha from the age of 17 onwards. However, before that unfortunately I used to miss most of my Salaah. 

My family wants me to go for Umrah but I don't feel it to be the right thing for me to join them, as I haven't completed my qadha salaah yet. I feel it's doesn't make sense to do that great but nafl amal when a compulsory amal is outstanding. I would feel extremely uncomfortable visiting the Kabah Shareef and Madinah, including the mubarak qabr of Nabi (sallallahu alaihi wasallam), and then conveying the durood with such major sins and unpaid debt on my shoulders. I understand that there is obviously barakah in Umrah, but there might be barakah in making qadha salaah as well (in my opinion). 

In addition, I find that my concentration and devotion to any nafl amal is weak and I always feel that I'm wasting time since I'm not prioritizing what is more important in the sight of Allah. Please advise.
