Re: Khalid bin Waleed controversy [split- Sahaba fan club]
^ maybe umar [ra] did not want to contradict what abu bakr [ra] did ....but its clear that umar[ra] from the beginning was not happy in giving command to people who had fought against the Prophet[pbuh] so this decision was expected.
also is the issue of Riddah war captives umar[ra] released them and allowed them to participate in wars of conquest.
but what USR I think is saying is that if a drastic action was taken against khalid at that time banu makhzum might have been deeply offended and many other quraishi meccans may have withdrawn their support to caliphate.
