I'm confused about the prayer you have to do for repentance?

[Zobia]

Assalumu Alaikum Wr Wb,
I was watching a video about how to repent on Islamic - tube, and it was said that to repent you have perform 2 units of prayer, it is known as the 'Prayer of Istighfar' , 'The Prayer of Forgiveness. But thing is, i don't know how to pray two units of prayer; is it just a normal 2 units of prayer? You know how when we pray Fajir and we say '2 rakkat namaz sunnat' when we are doing our 2 sunnat, well what do we say when we do our 'Prayer of Istighfar'? And straight after we read our 2 units of prayer we are told that we should read the dua 'Sayeedun Istighfar', would we read this while we are still in prayer, after we have completed our prayer? The video is below, i really need some help and if anyone can find me the du'a Sayeedun Istighfar' it would be really really helpful!

Wa'alaikum as'salaam wr wb,

The 2 units of prayer basically means to 2 rakah nawfil prayer. You are praying these 2 rakah nawfil in intention of istagfir so they are referred to as prayer of istagfar.

Here's the Dua you were asking about: http://www.ummah.net/Al_adaab/ilm_ul...istighfar.html

Here's transliteration:

Allaahumma anta Rabbee, laa ilaaha illaa anta, khalaqtanee, wa ana 'abduka, wa ana alaa 'ahdika wa wa'dika masta' ta' tu, a'oothu bika min sharri ma sana'tu, aboo'u laka bini'matika 'alayya, wa aboo'u bithambe, faghfirlee fa'innahu laa yaghfiru-th-thunooba illaa anta
