Ubaadah Ibn Somit(R.A)says:one day,when Ramadan is around the corner,Rosulullah(SAW)said"the month of Ramadan,month of mercy has come,in which God will show you his mercy,will decend on you his outstanding mercy in it,will ignore ur trespasses,he will answer ur prayers,God loves seeing u competing with good deeds in it and will be proud of you in the presence of his angels.so therefore,show ur good deeds to God,because the person that looses most in this month is the person who loses God's mercy"
