Can you tell me what they are?

Certainly! Here are a few common prayers of contrition and seeking forgiveness in Islam:

1. Istighfar: This is the simple yet powerful prayer for seeking forgiveness. The phrase "Astaghfirullah" (I seek forgiveness from Allah) can be recited repeatedly, individually or as part of your daily prayers.

2. Tawbah Prayer: This prayer involves performing two Rak'ahs of voluntary prayer, with the intention of seeking forgiveness and repenting from your sins. During the prayer, you can specifically mention the sins you are seeking forgiveness for and express your remorse.

3. The Prayer of Prophet Adam (pbuh): According to narrations, when Prophet Adam (peace be upon him) sought forgiveness from Allah after committing a mistake, he recited the following prayer: "Rabbana zalamna anfusana wa in lam taghfir lana wa tarhamna lana kunanna minal-khasireen" (Our Lord, we have wronged ourselves, and if You do not forgive us and have mercy upon us, we will surely be among the losers).

4. The Prayer of Prophet Yunus (pbuh): When Prophet Yunus (peace be upon him) found himself in the belly of the whale and in a state of distress, he called out to Allah and recited: "La ilaha illa Anta, subhanaka inni kuntu minaz-zalimeen" (There is no deity except You; exalted are You. Indeed, I have been of the wrongdoers).

These are just a few examples of prayers Muslims can recite for penance and seeking forgiveness. It is important to remember that the sincerity and intention behind these prayers are crucial, as true repentance involves a genuine desire to change and seek forgiveness from Allah.
