Abu Qatadah ( Radhiallaho anha ) reported : The Messenger of Allah ( Sallallaahu 'alaihi wasallam ) was asked about the observance of Saum ( fasting ) on the day of ‘Arafah (the day before Eid Adhuha).. He said, “It is an expiation (atonement) for the sins of the preceding year and the current year.” Abu Mas'ud 'Uqba ibn 'Amr al-Ansari al-Badri reported that the Messenger of Allah, (PBUH), said, "Anyone who shows the way to something good has the same reward as the person who does it." [Muslim] E.g. if you encourage someone to go for Salah, or pay Zakat and the person actually goes ahead and prays or pays Zakat, Allah will reward him for the good deeds and at the same time give you (the one that encouraged them to do good) an equal reward as he has given them- without decreasing what he gave them. So Encourage Other To Do Good And Refrain From Bad Deeds
