 The Prophet sallallahu alayhi wa alayhi wa sallam, he said in a hadith, Man sallah rak'atani lam yuhaddith nefsahu fihimah bi shay'in min ad-dunya ghufira lahuma taqaddam min dambih. Whoever prays two rak'ahs and their nefs does not, you know, you are not, you are not listening or giving the opportunity to your nefs to speak to you about things of the world, the reward for having that level of presence in nasada is that Allah forgives your previous sins. So once again Imam al-Ghazali is saying this is critical for the prayer to be accepted, to be of those people that Allah subhanahu wa ta'ala when they establish a true prayer they're transformed and they avoid al-Fahshat wa al-munkar in decency and wrongdoing by being present in the Salat, by not giving into the insinuations and the internal conversations of the nefs that take us into the dunya.
