not sure if i posted this before. there are some hadith regarding fasting on ashura which seem to contradict one another and also not make any logical sense. can someone reconcile please. they are as follows
1) there is a hadith in which aisha رضي الله عنه says the makkans used to fast on the 10th ( prior to hijra) and if i rememebr correctly the prophet used to keep this fast too
2) the prophet saw jews fasting in madinah and asked why, when told he said we have a greater right on Musa (as) so we will fast too
3) the sahaba told the prophet jews fast on the 10th, so prophet said if i live to next year il add one fast to it
1)what i want to know is if the prophet

2)n the 10years prophet lived in madinah how comes he only found out on the final year jews kept a fast?
3) if the jews told the prophet why they fasted why did the sahaba have to inform him and tell him we should be different hence fasting on 9th and 11th as well
ps the hadith of aisha رضي الله عنه i will try find it as im not 100% if she said rasoolullah

please respond with answers to questions i asked as opposed to sending long articles
