What are the supplications mentioned in the Holy Quran by prophets, messengers, and the righteous, and are prayers answered through them?

These are Quranic supplications, hoped to be answered, provided the conditions and etiquettes of supplication are met. These include: "Our Lord, accept from us; indeed, You are the All-Hearing, the All-Knowing," "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," "Our Lord, let not our hearts deviate after You have guided us," "My Lord, grant me from Yourself a good offspring," "Our Lord, forgive us our sins," "There is no deity except You; exalted are You. Indeed, I have been of the wrongdoers," "My Lord, expand for me my breast [with assurance]," "My Lord, increase me in knowledge," "My Lord, enable me to be grateful for Your favor," and other supplications mentioned in the Quran.
