I am working in MNC software company. Over here all employees, mostly non-Muslims, wish each other with "Good morning" and "Good night". And during special festival with "Happy Holi", "Happy Diwali" etc.
So, is this allowed in Islam? Can we wish them during ordinary days and during festivals?
Are there any alternatives to wishing them with "Good morning" and "Good night"?
EDIT
Thanks Everyone, i got answer for secular greetings (good morning), that we can wish them,
But can we wish religious greetings (happy diwali , happy holi,...) ?
Final EDIT
Thanks everyone..
I Got answers of my questions.
Yes, We can greet non-muslims with Good Morning or Good Night.
But, We can not wish non-muslims to on their Religious Festival.
