Is this du’a found in a Hadith?
اللهم اجعل صيامي فيه صيام الصائمين وقيامي فيه قيام القائمين ونبهني فيه عن نومة الغافلين واعف عني ياعافي المجرمين
Allahummaj’al siyami fihi siyamas sa-imin wa qiyami fihi qiyamal qa-imin wa nabbihni fihi ‘an nawmatil ghafilin wa’fu ‘anni ya ‘afiyal mujrimin
Answer
I have not come across this du’a in any Hadith source.
However, since the meaning of this du’a is correct, you may recite the du’a without deeming it a du’a of Nabi (sallallahu ‘alayhi wa sallam).
Translation
O Allah! On this day, make my fast the fast of those who fast [sincerely/perfectly] and my standing in [Salah] the standing of those who offer Salah [sincerely/obediently], awaken me on this day from slumber of the unmindful and forgive me O the One who forgives the sinners.
And Allah Ta’ala Knows best.
