hhmm but sis we r saying name of Allah so how can we say jazakillah for male nd female its jazak Allah onlySister i wont mind suggestion. I really appreciate them. Firstly i was used to say Jazak ALLAH. and then one day i learned from my sister about the detail meaning and understanding.
For you as well: http://towardsorigin.com/jazakallah-and-jazakillah/
In short : JazakAllah is used for male
Jazakillah is used for female
the answer will be also the same
wa iyyaki for female
wa iyyaka for male
hope that helps
