Mentioning the name of Allah (swt) expels the evil whispers of humans and devils. Moreover, it is basic in all the worshipping deeds. When Allah (swt) is mentioned the devil withdraws. For such Allah (swt) says:

  {فَإِذَا قَضَيْتُم مَّنَاسِكَكُمْ فَاذْكُرُوا اللَّهَ كَذِكْرِكُمْ آبَاءَكُمْ أَوْ أَشَدَّ ذِكْرًا}

(And when you have completed your rites, remember Allah like your [previous] remembrance of your fathers or with [much] greater remembrance.) (Al-Baqara: 200)

Allah (swt) also says:

 { فَإِذَا قَضَيْتُمُ الصَّلَاةَ فَاذْكُرُوا اللَّهَ قِيَامًا وَقُعُودًا وَعَلَىٰ جُنُوبِكُمْ }

(And when you have completed the prayer, remember Allah standing, sitting, or [lying] on your sides.) (An-Nisaa: 103)

Remembering Allah (swt) means to be always with Him and does not forget Him. They are not mere words said by tongues. Your heart has to be shaken and feels of Allah’s watching, caring, giving and fearing of Him (swt) as well.

فَصَلَّى  (prays): It is mentioned that the prayer meant here is Eid prayer. But we take the general meaning which is the prayer as a whole which includes bowing, prostration, standing and reading.
