There are many Hadeeths about the great reward and ample blessings and gifts for the person who performs Salah. Also the emphasis on praying Salah with dedication as we read in the first verses in Sura Al-Mo'minoon.

You can read in Thawab Al-A'maal by al-Shaikh Al-Sadouq many narrations in this regard e.g. When the believer performs Salah, the angles cover him with a cover of mercy, and his sins will fall down like the leaves of the tree in autumn. If the believer knows the mercy on him while he is praying, he will never leave his Salah. Prayers cleans the book of  deeds and removes the bad deeds, etc.
