In the "Taj Al-Aroos" or "The Crown of the bride" by Ibn Ata'llah As-Sakandari (may Allah show him mercy) he states about the presence of heart in the prayer;
"The likeness of one who prays, without presence of heart, is like someone sending a King, a gift of one hundred empty boxes; thus deserving his punishment.
Whoever prays with presence of heart is like someone giving the king a precious sapphire; worth a thousand gold coins. The king will always remember him because of it."
