advantage is that this Salah will become a source of our forgiveness and salvation on the day of judgment.

Salvation for those who perform Salah with Khushu and Khuzu

The Holy Nabi صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم has stated, Allah عَزَّوَجَلَّ has made five prayers obligatory. If anyone performs ablution for them properly, offers them at their right time, and observes perfectly their bowings and prostrations with Khusu and Khuzu (humility of body and heart), it is upon the Mercy of Allah عَزَّوَجَلَّ that He عَزَّوَجَلَّ will pardon him; if anyone does not do so, there is no guarantee for him on the part of Allah عَزَّوَجَلَّ; He عَزَّوَجَلَّ may pardon him if He wills, and punishes him if He عَزَّوَجَلَّ wills. (Sunan Abu Dawood, book of Salah)

Each Salah is expiation for the past sins

Narrated by Sayyiduna Haris رَضِىَ اللهُ تَعَالٰی عَـنْهُ that Sayyiduna Usman رَضِىَ اللهُ تَعَالٰی عَـنْهُ was sitting with us and Muazzin came. Sayyiduna Usman رَضِىَ اللهُ تَعَالٰی عَـنْهُ had some water brought and performed ablution. He رَضِىَ اللهُ تَعَالٰی عَـنْهُ said, ‘ I have seen the Blessed Rasool صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم performing ablution in the same way and I have heard  the Holy Nabi صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم saying that, ‘One who performs ablution the way I do and performs Zuhr Salah, Allah عَزَّوَجَلَّ forgives his sins, i.e., those sins which are committed between the Fajr Salah and Zuhr Salah, when he performs ‘Asr Salah then Allah عَزَّوَجَلَّ forgives his sins committed between the Zuhr Salah and ‘Asr Salah, when he performs Maghrib Salah then Allah عَزَّوَجَلَّ forgives his sins committed between the ‘Asr Salah and Maghrib Salah, when he performs Isha Salah then Allah عَزَّوَجَلَّ forgives his sins committed between the Maghrib Salah and Isha Salah, then he may stay laying the whole night and after waking up performs Fajr Salah, his sins committed between the Isha Salah and Fajr Salah are forgiven and these are the virtues which will keep the evils away.
