But this rule is specifically applicable in a circumstance where this is the only way of feeding milk to the child - (as an obligatory precaution).

Issue 1739: * The 1st day of a month is established in the following four ways:
(i) If a person himself sights the moon.

(iii) If two just (Adil) persons say that they have sighted the moon at night. The first day of the month will not be established if they differ about the details of the new moon. This difference can be either explicit or even implied. For example, when a group of people goes out in search of a new moon and none but two Adils claim to have seen the new moon, though, among those who did not see, there were other Adils equally capable and knowledgeable, then the testimony by the first two Adils will not prove the advent of a new month.

Issue 1744: * If the first day of a month is proved in a city, it is also proved in other cities if they are united in their horizon. And the meaning of having a common horizon in this matter is that if new moon was sighted in a city, there would be a distinct possibility of sighting it in the other cities, if there were no impediments, like, the clouds etc.
Issue 1745: The first day of a month is not proved by a telegram except when one is sure that the telegram is based on the testimony of two Adils, or on a source which is reliable in the eyes of Shariah.

But if even that is not possible, he may consider a month which he strongly feels to be Ramadhan and fast; however, he should keep that month in view so that if it later transpires that he kept fasts before Ramadhan, he will give the qadha. And if it transpired that it was Ramadhan or after it, he does not have any liability of qadha.

Issue 1752: * If a person knows that fasting is not harmful to him, he should fast even if his doctor advises that it is harmful. And if a person is certain or has a feeling that fasting is harmful to him, he should not fast even if the doctor advises for it, and if he fasts in these circumstances, his fast will not be valid if it turns out that the fast was actually harmful, or if it was not kept with the Niiyyat of Qurbat.

If a person observes a Mustahab fast, it is not obligatory on him to complete it. In fact, if one of his brethren-in-faith invites him to a meal, it is Mustahab that he accepts the invitation and breaks the fast during the day time even if it may be after Zuhr.
Issue 1758: It is Mustahab for the following persons that even if they may not be fasting, they should refrain from those acts in the month of Ramadhan which invalidate a fast:
(i) A traveller who has committed an act during his journey which makes a fast void and reaches his hometown before Zuhr, or the place where he intends to stay for ten days.
(ii) A traveller who reaches home after Zuhr or at a place where he intends to stay for ten days. The same rule applies if he reaches such places before Zuhr and if he has already broken his fast while journeying.
(iii) A patient who recovers after Zuhr or even if he recovers before noon, though he may have committed acts which invalidate fast. And if he has not committed any such act, then his obligation has been explained in rule no. 1576.
(iv) A woman who becomes Clean (tahir/pak) from Haidh or Nifas during day time.
Issue 1759: It is Mustahab that a person breaks his fast after offering Maghrib and Isha prayers. However, if he feels terribly inclined to eat, so much that he cannot concentrate on the prayers, or if someone is waiting for him, it is better that he should break his fast first and offer the prayers later. However, as far as possible, he should try to offer the prayers during the prime time (Fadheelat).
