Looking in the Quraan while performing salaah

Q:

1. Is it permissible to hold the Quran in one's hand in Salah for reading so that one can read unknown surahs after sure fateha.

2. Is it permissible to read the whole tarawih prayers (alone) and in other prayers.

3. If not, could you please tell me why we should not do it.

4. Why do people in the haram hold the Quran in their hand and read or read from the phone in their salah.

Using zakaat funds to pay for expensive medication

Q: I am a dialysis patient requiring medication every month for approximately 1 year and if not taken, it can be life threatening. Due to the price of these medications being expensive and way out of my budget, so a Muslim medical organisation offered to pay for the medication but through zakaat funds. My question is that despite being sahib-e-nisab, will it be permissible to accept it in this dire circumstance?
