Wanted to share dua from hadith on sahih al-bukhari I came across with you. It is a dua for forgiveness also referred to as sayyidul istighfar or the most powerful dua for forgiveness.

Allahumma anta Rabbi la ilaha illa anta, Khalaqtani wa ana `Abduka, wa ana `ala `ahdika wa wa`dika mastata`tu, A`udhu bika min Sharri ma sana`tu, abu’u Laka bini`matika `alaiya, wa abu’u laka bidhanbi faghfir lee fa innahu la yaghfiru adhdhunuba illa anta.”

The Prophet (pbuh) added. “If somebody recites it during the day with firm faith in it, and dies on the same day before the evening, he will be from the people of Paradise; and if somebody recites it at night with firm faith in it, and dies before the morning, he will be from the people of Paradise.”

Reference: Sahih Al-Bukhari Book 80, Hadith 3.

Will be uploading video on recitation and have written more extensively in article below.
