أحسن الله إليك أستاذنا What should a person do if they haven't fasted before and therefore have 120 days left? Do they have to fast all of these days until the next Ramadan? Or can they fast beyond Ramadan?

Ustadh AbdulAziz al-Haqqan
Do your best in finishing before ramadhan if u can and there is no harm for you. It is doable in sha'a Allah.
