Sleeping partner fixing his share of the profit more than his capital investment

Q: Ayyoob and Junaid each contributed R200 000 as their capital investment to start a business partnership.

Intention when making qadha of many salaahs

Q: I have qadha salaah from a certain year. I have read salaah in between but I'm not sure when my haiz fell during the year as well as which salaahs I read.

My question is, my intention for the qadha should be made from a specific date that my salaah became obligatory and each date so on till the current date, or should my intention be that, from the first of all the qadha I have right up until a number I assume I missed.
