Good morning

Here are the ways you can wish somebody a good morning.
The most "traditional" way to do it is to say:

صباح الخير
Saba7 el-kheir
(7 stands for ح)

You can answer it by saying saba7 el-kheir too,  or by saying:

صباح النور
Saba7 en-nur
Which literally means morning of light.

However there are some much more "Egyptian" ways to say "good morning". You can say:

صباح الفل
Saba7 el-ful

Or morning of Arabian jasmine
(make sure that the u sound is short, otherwise "jasmine morning" will turn into "bean morning").
There is also

صباح الياسمين
Saba7 el-yasmin 

Morning of jasmine
Or:

صباح الورد
Saba7 el-ward

Morning of roses..
There are more flowery, fruity and sugary expressions like that. Egyptians sometimes just come up with new ways to say "Good morning" depending on their current mood.
Evening in Arabic is

 مساء
Masa2

Replace word saba7 with masa2 and you will know  how to say "good evening".
