Many variations... which is correct?

When to use what?

- Jazakallah
- Jazakallah khair
- Jazakallahu khair
- Jazakallahu khairan



I'm sure I've seen more, but just can't remember the others

From what i know:

JazakAllah = May Allah reward you.
JazakAllah Khayr = May Allah reward you greatly.
JazakAllahu Khayr = same as above
and JazakAllah Khayran = im not too sure

Jazakumullah = for more than one person

but Admin will know more about this inshAllah

1: When replying to 3 or more people (male) you say Jazakumullahu Khair
1.1: If you're replying to a group of females and one man is there as well then you say Jazakumullahu khair
2: When replying to 3 or more females you say JazakunnAllah

But you never find anyone using anything other than jazakallahu khair.

I've done this lesson countless times but i'll do it again,

Jazaahu - singular absent male
Jazaahuma - dual absent male

Jazaaki - singular present female
Jazaakuma - dual present female
Jazaakunna - plural present female

Jazaanaa - plural 1st person

Admin wrote that btw on Ummah not me

okay but could I say Jazakallahu khair to a group of people?

ex: Jazakallahu khair kids for your replies

Gramattically it will not be correct to say so, you'd have to say Jazakumullahu khair, but i suppose if you don't know arabic and speaking to people who don't know arabic then i suppose you could say jazakallahu khair if they assume it to refer to them all.

Since this is a jazakallah thread i just want to clear up one of my earlier mistakes.

My assertion was that it was fine to say 'jazakallah' to both males and females, which is wrong, i didn't really think it through, but after doing some thinking i realised my mistake, it was a blatantly obvious one which i would have to be blind to miss, but somehow it managed to elude me.

My train of thought was that you're saying "Jazak-Allah", hence why i said it's okay to say to a female as well assuming that the kasrah of the kaaf had been made mahzoof, but i was quite mistaken, for a word cannot be left harkat-less in the middle of a sentence, thus "jazakallah" is actually "Jazaka-llah", therefore saying 'jazakallah' to a female will be gramatically incorrect.

I know the majority of you won't know what i'm speaking about, so in short, 'jazakallah' is for a man and 'jazakillah' is for a woman.
