Asking Forgiveness
Whosoever shall recite this Dua in the last ten nights after every Wajib and Sunnah Salaah, Allah Subhaanahu Wata’ala will forgive his sins committed in this holy month of Ramadhan and shall safeguard him from committing other sins in the remaining days:
Bismillaahir-Rahmaanir-Raheem.
Allaahummaa Addi Annaa Haqqa Maa Madhaa Min Shahri Ramadhan
Waghfir Lanaa Taqseeranaa Feehi Watasallamhu Minnaa Maqboolan
Walaa Tu’aakhidhnaa Bi Israafinaa Alaa Anfusinaa
Waj’Alnaa Minal Marhoomeen Walaa Taj’Alnaa Minal Mahroomeen.
O Allah, let us make amends and make-up for the past days of the month of Ramadhan.
Ignore our mistakes. Acknowledge that which we have submitted as to your liking.
Do not take hold of us for the overindulgence and extravagance we employed to overindulgence, include us among those who have been dealt with mercifully, and not among those excluded.
Ameen!

Very inspiring.Jazak Allah.
