The Prophet (صلى الله عليه و سلم) said:
“الصوم يوم تصومون و الفطر يوم تفطرون و الأضحى يوم تضحون”
The day of fasting is the day you all fast. And the day of breaking the fast is when you all break your fast. And the day of sacrifice is when you all sacrifice.
Narrated by Imam At Tirmidhi in his collection.
Shaikh Al Albani said (1/443):
Imam At Tirmidhi said after the Hadeeth:
“And some of the people of knowledge have explained this Hadeeth saying that it mean that fasting and breaking the fast is done with the Jama’ah (the Muslim country with its ruler) and the majority of people.”
As San’aani said in Subulus Salaam:
“It is an evidence that the establishment of ‘Eid goes according to the agreement of the people and that the one who is alone with his knowledge of the day of ‘Eid must be in agreement with other than him (regarding the day of ‘Eid). And their ruling is upon him regarding the prayer, the breaking of the fast and sacrifice.
Imam Ibn Qayyim Al Jawzeeyah said:
“… and it is said: if one witness sees the moon and the judge (of the country) does not accept his sighting then he should refrain from fasting as is the case with others who have not began (due to the judge not ruling by his sighting).”
Abul Hasan As Sindi said:
“Its meaning, from what is apparent, is that these matters are not up to individuals. It is not for them to separate themselves in these matters but rather it is up to the Muslim leaders and those who follow him. It is therefore upon each individual to follow their leaders and the majority of the people.”
Shaikh Al Albani then said:
“I say: And this is the apparent meaning one gets from the Hadeeth and what supports it is what ‘Aisha (رضي الله عنها) used as evidence against Masrooq when he did not fast on the day of ‘Arafat fearing that it was the day of sacrifice. She then clarified to him that his opinion had no significance and that it was upon him to follow the majority of people when she said:
“النحر يوم ينحر الناس و الفطر يوم يفطر الناس”
“The day of sacrifice is when everyone sacrifices and the day of breaking the fast is when everyone breaks the fast.”
I (Shaikh Al Albani wrote) say: This is what is appropriate according to the legislation with one of its goals being unity among the people and distancing them from that which would cause disunity from individual opinions. Therefore the opinions of an individual have no significance in the legislation, even if it is correct according to his opinion, in group worship such as fasting, ‘Eid and the congregational prayer…”
Likewise many of the scholars and Mashayikh have advised us to go with the majority when fasting and breaking the fast. From them Shaikh Wasiyullah Al ‘Abbas, Shaikh Abu ‘Amr Al Haajoori, Shaikh Zaayed Al Wassabi, Shaikh ‘Abdul Hameed Al Haajoori, Shaikh ‘Adnaan Al Masqari, Shaikh Muhammad Al Maaliki and others.
This is also the advice of other scholars such as Shaikh Saalih Al Fawzaan, Shaikh Yahya Al Haajoori etc. May Allah ta’ala bless us to follow the Qur’an and the Sunnah according to how our Salaf and ‘Ulama understood it.
