What are the best comprehensive supplications that can be repeated at all times during the month of Ramadan?

The best supplication is what is mentioned in the Holy Quran, such as the words of Allah Almighty: "Our Lord, give us in this world [that which is] good and in the Hereafter [that which is] good and protect us from the punishment of the Fire."

And what is mentioned in the Prophetic Sunnah, including: - "The best of remembrance is: 'There is no god but Allah,' and the best of supplication is: 'Praise be to Allah.'" - "The best words after the Quran are four: 'Glory be to Allah,' 'Praise be to Allah,' 'There is no god but Allah,' and 'Allah is the Greatest.'" - "O Allah, I ask You for well-being in this world and the Hereafter." - On Laylat al-Qadr (the Night of Decree): "O Allah, indeed You are Forgiving, You love forgiveness, so forgive me." - The master of seeking forgiveness (Sayyid al-Istighfar): "O Allah, You are my Lord, there is no god but You. You created me and I am Your servant, and I am on Your covenant and promise as much as I am able. I seek refuge in You from the evil of what I have done. I acknowledge Your blessings upon me, and I acknowledge my sin, so forgive me, for none forgives sins except You."
