Is it possible for prayer to be written down as sins instead of rewards due to unintentional preoccupation with worldly matters, and is what Al-Ghazali mentioned correct?

The phrases mentioned were not found in Al-Ghazali's books, and their source needs to be clarified for discussion. If their attribution is correct, they might relate to Al-Ghazali's view on the obligation of humility (khushu') in prayer, a position in which he differed from the majority of scholars who consider humility commendable and believe that prayer is not invalidated by the dominance of thoughts.
