Prayer strengthens a weak soul | A soul that remembers Allah

Function of Prayer in Islam
In Surah Al Ankabut verse 45 Allah says
اتْلُ مَا أُوحِيَ إِلَيْكَ مِنَ الْكِتَابِ وَأَقِمِ الصَّلَاةَ إِنَّ الصَّلَاةَ تَنْهَى عَنِ الْفَحْشَاء وَالْمُنكَرِ وَلَذِكْرُ اللَّهِ أَكْبَرُ وَاللَّهُ يَعْلَمُ مَا تَصْنَعُونَ ﴿٤٥﴾
45. Recite, [O Muhammad], what has been revealed to you from the Book and establish prayer. Indeed, prayer prohibits immorality and wrongdoing, and the remembrance of Allah is greater. And Allah knows that which you do.
