Requirements for fight

Re: Requirements for fight

Brother

Jabla bin ayham head of ghassanids became murtad in hadrat umer:razi: time whereas the offensive was started in hadrat abu bakr:razi: time. This is what i know (i have to check books for this) , kindly confirm if my understanidng is correct or not.

Secondly if that was the main issue then why this was not the condition that stop this support and we will not fight?, how many emissaries were sent to romans to stop ghassanids? how many offensives were made against ghassanids and why not stop when muslims won battle of yarmouk?

To me this does not appear to be the sole reason for the attack, even the sermon given by hadrat abu bakr :razi: as quoted in al waqdi book hint in a different direction.
