  Let $f : A \rightarrow B$ be a ring homomorphism and $J$ be an ideal of $B$.
In this paper, we give a characterization of zero divisors of the amalgamation
which is a generalization of Maimani's and Yassemi's work (see \cite{y}). Also,
we investigate the transfer of Pr\"ufer domain concept to commutative rings
with zero divisors in the amalgamation of $A$ with $B$ along $J$ with respect
to $f$ (denoted by $A\bowtie^fJ),$ introduced and studied by D'Anna,
Finocchiaro and Fontana in 2009 (see \cite{AFF1} and \cite{AFF2}). Our aim is
to provide new classes of commutative rings satisfying this property.
