Staying Connected With Allah:
Muslims who realize that Allah Almighty is their Lord and the Giver of everything, they try to develop a relation with Him and wish to stay connected with Him as much as possible so that their relation grows strong. Salaah can effectively help in achieving so, as Allah says in Quran:

فَإِذَا قَضَيْتُمُ ٱلصَّلَوٰةَ فَٱذْكُرُوا۟ ٱللَّهَ قِيَـٰمًا وَقُعُودًا وَعَلَىٰ جُنُوبِكُمْ ۚ فَإِذَا ٱطْمَأْنَنتُمْ فَأَقِيمُوا۟ ٱلصَّلَوٰةَ ۚ إِنَّ ٱلصَّلَوٰةَ كَانَتْ عَلَى ٱلْمُؤْمِنِينَ كِتَـٰبًا مَّوْقُوتًا
When you finish your Salah (prayers) remember Allah whether you are standing, sitting or reclining; then as soon as you are safe (out of danger) establish regular Salah in full. Surely Salah are made obligatory for the believers at their prescribed times. [An Nisaa 4: 103]

Therefore, performing prayers is a means of developing a connection with Allah and when a Muslim does so five times a day, then the consequent relationship is to naturally grow strong.

Protection from Shaytaan:
Shaytaan is an open enemy of believers and all what he tries is to make people go astray from the path of righteousness and go down in the path of oblivion and darkness. Shaytaan tries to tempt a person in all the possible ways and when a person once listens to him, he gradually lures them down further into the pit of darkness. Therefore, seeking protection from Shaytaan is also imperative for a Muslim. In Quran Allah Almighty says:

إِنَّمَا يُرِيدُ ٱلشَّيْطَـٰنُ أَن يُوقِعَ بَيْنَكُمُ ٱلْعَدَٰوَةَ وَٱلْبَغْضَآءَ فِى ٱلْخَمْرِ وَٱلْمَيْسِرِ وَيَصُدَّكُمْ عَن ذِكْرِ ٱللَّهِ وَعَنِ ٱلصَّلَوٰةِ ۖ فَهَلْ أَنتُم مُّنتَهُونَ
Shaytaan desires to stir up enmity and hatred between you with intoxicants and gambling and to prevent you from the remembrance of Allah and from Salah (prayers). Will you not abstain? (Al Maida 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 and when these temptations are resisted for long the result is one not falling prey to Shaytaan ever again.

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 if a Muslim starts being like other people, he or she goes down the road of darkness. 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 Salaah, as it will help in combating lewdness, as Allah says in Quran:

إِنَّ ٱلصَّلَوٰةَ تَنْهَىٰ عَنِ ٱلْفَحْشَآءِ وَٱلْمُنكَرِ
Indeed, prayer prohibits immorality and wrongdoing [Al Ankabut 29: 45]
Therefore, a Muslim must consider Salaah as an effective weapon when it comes to fighting lewdness and evils of all sorts.
