Rule for specifying days when performing qadhaa fasts

Question:

assalamualaikum

due to a health condition i have to make up fasts from 4 years ago, I wrote down the dates on a paper, do I have to look at what date I'm making up at sehri time before starting the fast to make the intention count, or can I just have niyyah that today I'm going to make up the next fast that I need to makeup that I wrote on the paper?  If I dont specifiy my intention of the exact date does that invalidate the qadha and turn it into a nafl fast?

بسم الله الرحمن الرحيم

Answer:

Wa ‘alaykum as salām wa raḥmatullāhi wa barakātuhu,
 
It is not necessary to specify the exact date when intending a qadha fast. Rather, it would be sufficient that one merely intends to make up the last necessary qadha fast they are responsible for.

والله اعلم

Allah subhanahu wa ta'ala knows best.
