The pious Maliki scholar Abdur Rahman al-Akhdari who died in the 10 century A.H mentions in his famous work known as al-Akhdari :
Prayer beholds an illuminating divine light which illuminates the hearts of those who perform prayer and none obtain it except those who humble themselves in fear before Allah (during prayer). If you therefore, come to perform prayer, empty your heart form all worldly matters and engage yourself in seeking awareness of your Lord for Whose Countenance you pray.
Keep in mind that Prayer in fact is a act of awe and humility before Allah, The Exalted by standing, bowing, prostrating. Likewise, unequalled respect and esteem for Him is shown by means of takbir, glorification (tasbih) and remembrance and adoration (thikr).
Thus, guard your prayer for it is the greatest form of worship. Do not allow Shaytan to play with your heart and distract you from your prayer thereby obliterating your heart and depriving you from tasting the divine light that prayer provides. Be forever mindful; humbling yourself in prayer because it protects from all shameful and blameworthy deeds. Seek help through Allah for He is the best to seek help from.
