Fasting

There is no sin as the fasting of such a day is voluntary and not mandatory.

There is no expiation except making up for the days missed. There is no feeding of the poor.

You can fast any number of days of this month, even if you fast one day only.

This doesn’t affect your fasting but it affects your prayers. You shouldn’t delay your Fajr until after sunrise.

If the illness is permanent, one should feed one poor person for everyday missed. If the illness is curable, one should wait until he is well and then make up for the days missed.

The Prophet salla Allahu alaihi wa sallam has said that whenever a person east or drinks while fasting due to forgetfulness, it is Allahu who has fed him. Therefore, your fasting is correct.

What you had done was a real mistake and major sin. You should seek Allah’s forgiveness and you should make up for the days missed in Ramadan. You should also break the news to your parents and family and tell them that you had become Muslim.

They wish that Allah accepts the good deeds offered in Ramadan and also on the 10 days of Hijjah.

No.

There isn’t any supplication to be said. You simply intend it in your heart or by eating the pre-dawn meal.
