A Niyyah is in the Heart: The Prophet (sallallahu alaihi wa-sallam) said,The activities are Innama (just, sureness) attached to the aims and each individual will gain what he intended. [Agreed upon] A Niyyah is the determination (goal) of the heart. The spot of the expectation is the heart and reporting the Niyyah resoundingly is a development (Bidah) that has no premise in the Quran and the Sunah.
A Niyyah for the Fard (mandatory) Fasts: It is required to have the goal for the compulsory fasts preceding the sunrise (dawn) as the Prophet (sallallahu alaihi wa-sallam) said, He, who does not set out to fast before it is Fajr, then there is no fast for him [Reported by Abu Dawood.
A Niyyah for the Nafl (intentional) Fasts: One may plan to fast deliberately even after the break of day, not at all like the compulsory fasts, gave that one has abstained from eating, drinking, and sex. Proof for this decision is the Hadeeth of Aisha (radhi allahu anha), when she described, The Prophet (sallallahu alaihi wa-sallam) came to visit me one day and asked, Do you have anything (to eat)?I said, No. He answered, Then, I am fasting.
In the event that a man leaves on a compulsory fast, for example, compensating for a day missed in Ramadaan, or satisfying a promise, or fasting as a demonstration of appeasement (kafaarah), he must finish the fast, and he is not allowed to break it unless he has a legitimate reason for doing as such. On account of a naafil fast, "the individual who is watching a deliberate fast has the decision either to finish the fast or to break it" (reported by Ahmad, 6/342) – regardless of the fact that there is no motivation to break it. The Prophet (peace and gifts of Allaah be upon him) got up fasting one morning, then he ate. (As reported in Saheeh Muslim, in the account of the al-hais (a kind of sustenance) that was given to him as a blessing when he was in 'Aa'ishah's home; no. 1154, 'Abd al-Baaqi). Yet, will the individual who breaks his fast for reasons unknown be remunerated for the fasting that he has officially done? A portion of the researchers say that he won't be remunerated (al-Mawsoo'ah al-Fiqhiyyah, 28/13), so it is better for the individual who is watching a deliberate fast to finish it, unless there is a substantial, squeezing purpose behind him to quit fasting.
