Can anyone of you wonderful guys tell why this doesn't work?

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{matrix,arrows,decorations.pathmorphing}
\usepackage{tikz-cd}

\newcommand{\cmd}[1]{#1}

\begin{document}
  \cmd{%
    \[
      \begin{tikzcd}
        A \arrow{r}{f} & B \\
      \end{tikzcd}
    \]
  }
\end{document}

while

\[
  \begin{tikzcd}
    A \arrow{r}{f} & B \\
  \end{tikzcd}
\]

works perfectly outside the \cmd?

    \begin{tikzcd}[ampersand replacement=\&] and use \& instead of & – egreg May 17 '17 at 11:22

    I'm voting to close this question as off-topic because it is solved in the first comment. – Sebastiano Jul 31 '18 at 19:34
