Forgiveness is to do Astaghfaar for all sins committed so far by Muslims especially in the second Ashra of Ramadan and to repent unto Allah. Do Astaghfaar, feel sorry, desist from committing it again, and make sure not to fall for the same sin again.Dua for the second Ashra is:

Translation:  “I seek forgiveness from Allah, my Lord, from every sin I committed”

–    Days Of Maghfirah

These are the days of Maghfirah and in the mid of Ramadan Allah’s forgiveness is at peak. He forgives only those who prostrate in front of Him with ashamed spirit and pledge in heart not to do the same again ever. Do Tauba as Allah loves those who repent on their sins, verily He is the only forgiver.

–    Be Kind – Forgive All

While you are asking for Allah’s forgiveness in this Ashra make sure that you do the same to our fellow Muslims by adopting alike trait of your Lord and let forgive them for all their deliberate mistakes.
