Doaa after prayer

A supplication after the prayer that was not explicitly and clearly stated in the noble Prophet’s Sunnah and there was no hadith of that definitively, and supplication as we know is in prostration or after the last tashahhud during the prayer or after standing up from kneeling, and a supplication after the prayer may be performed by some who we think is answered because it is He came after a great worship and one of the pillars of Islam, which is prayer, and the Prophet, peace and blessings be upon him, did not explicitly repeat a supplication after the prayer, but he used to plan every prayer to ask Allah for forgiveness three times and praise God 33 and praise God 33 and Allah 33 and complete the hundred by saying there is no God but God
