Prayers are such tools which could change your fate. In the Holy Quran Allah (The Omnipotent) says that I please to that person who constantly ask me for giving.
Whensoever you offer prayers, or you are in free time ask Allah to forgive you, Seek refuge of Allah, constantly seek forgiveness of Allah.
Allah (The Omniscient) much likes that person who prays to him, and who seeks his refuge.
May Allah (The Omnipresent) bless us with this ability to prays him and to Ask from him.
