Starting tmux with certain command inside of bash script

I ran into problem when tried to start tmux inside of bash-script. The following script is sample of the problem.

tmux new-session -d -s main
tmux send-keys -t main 'ls ~/' C-m
tmux attach-session -d -t main

This script works correct - it started tmux with list of ~/ directory. Then I tried to start same command (ls ~/) as a variable

tmux new-session -d -s main
foo="'ls ~/'"
tmux send-keys -t main "$foo" C-m
tmux attach-session -d -t main

However, It didn't work. I have got the following message

'ls ~/'
$ 'ls ~/'
-bash: ls ~/: No such file or directory

What is the reason of this problem and how to fix it?

You can't stick quotes inside quotes and have the shell remove them for you correctly.

See mywiki.wooledge.org/BashFAQ/050 for a full discussion on this.

Drop one set of the quotes there.

Either foo="ls ~/" or foo='ls ~/' but not both.
