The Importance of Salaah in General
Allah commands the believers in the Quraan to safeguard the obligation of Salaah as well as establish it in their lives. Allah mentions “Safeguard your Salaah – especially the middle Salaah (Asr Salaah).” In another verse, Allah says, “Establish Salaah for My remembrance.”

Of course, there is great benefit in whatever Allah advises us to do. Allah is not in need of us performing Salaah for his authority and grandeur to remain. When we perform Salaah, we perform it for our own benefit. Some of these benefits are…
Protection From Shaytaan:

Shaytaan is an open enemy of believers and all what he tries is to make people go stray from the path of righteousness and go down in the path of oblivion and darkness. Therefore, seeking protection from Shaytaan is also imperative for a Muslim. In Quran Allah Almighty says:

إِنَّمَا يُرِيدُ الشَّيْطَانُ أَنْ يُوقِعَ بَيْنَكُمُ الْعَدَاوَةَ وَالْبَغْضَاءَ فِي الْخَمْرِ وَالْمَيْسِرِ وَيَصُدَّكُمْ عَنْ ذِكْرِ اللَّهِ وَعَنِ الصَّلَاةِ ۖ فَهَلْ أَنْتُمْ مُنْتَهُونَ
Shaytaan only wants to cause between you animosity and hatred through intoxicants and gambling and to avert you from the remembrance of Allah and from prayer. So will you not desist? (5:91)

Therefore, not offering prayer is actually falling into the prey of Shaytaan, whereas those who try to offer and establish prayer are actually resisting his temptation.

Prevention From Lewdness:
In life, a Muslim gets exposed to all sorts of environments and people, all of which have a direct impact on the personality of the person. There is no denying the fact that the current plight of the people of the world is miserable where they are more prone towards ills and lewdness compared to goodness. Thus, in order to prevent one’s self from all the lewdness that is common in the world of today, a Muslim must find refuge in Salah as it will help in combating lewdness, as Allah says in Quran:

اتْلُ مَا أُوحِيَ إِلَيْكَ مِنَ الْكِتَابِ وَأَقِمِ الصَّلَاةَ ۖ إِنَّ الصَّلَاةَ تَنْهَىٰ عَنِ الْفَحْشَاءِ وَالْمُنْكَرِ ۗ وَلَذِكْرُ اللَّهِ أَكْبَرُ ۗ وَاللَّهُ يَعْلَمُ مَا تَصْنَعُونَ
Recite, [O Muhammad], what has been revealed to you of 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. (29:45)

Therefore, a Muslim must consider Salaah as an effective weapon when it comes to fighting lewdness and evils of all sorts.
