Question Summary:
I didn’t perform ghusl after masturbating; are my fasts accepted?

Question Detail:

If one masturbates on the 5th day of Ramadhan and did not take ghusl because they were unsure whether ghusl was necessary after this heinous act, then are the following 25 fasts accepted or must Qadha be made for the fasts plus the one of the 5thRamadhan?

Answer :

In the Name of Allah, the Most Gracious, the Most Merciful.
 
As-salāmu ‘alaykumwa-rahmatullāhiwa-barakātuh.
 
The following 25 fasts will be valid even if a person does not perform ghusl after masturbating. He will, however, have to do Qadha of the 5^th fast if he masturbated whilst fasting.[1]
 
And Allah Ta’āla Knows Best
