Please be tolerant of muslims who do not espouse the exact same views as yourself.
Celebrating occasions other than Eid-ul-Fitr and Eid-ul-Adha are not proven by the hadith. Since Mohammed (PBUH) did not celebrate occasions other than the mentioned two, we cant celebrate them as well.
‘Aayshah reported that the Prophet sallallaahu 'alayhi wa sallam said:
"
For every people there is a feast and this is our feast." [Sahih Al-Bukhari: (vol. 5, no. 268).]
"
Allâh has given you better than those feasts: the ‘Eid-ul-Adh-haa (Feast of Sacrificing), and ‘Eid-ul-Fitr (feast of Breaking the fast)." [Sunan An-Nasaaee: English translation: (vol. 2, p.333, no. 1559), Sunan Abu Dauwud: English translation: (vol. 1, p.293, no. 1130). It is authenticated by Shaykh Al-Albaanee in Saheeh Sunan Aboo Daawood: vol. 1, p. 210, no.1004.]
Umm Salamah said the Prophet used to fast on Saturdays and Sundays, and when asked he said: "
They are two days of Mushrikeen’s holidays so I like to oppose them in their ceremonies." [Musnad Imaam Ahmad.]
There are no two opinions on this. For those who still want to adulterate the principles and guidlines of Islam, they should consider the following ahadith on this matter.
Jaabir reported that the Prophet sallallaahu 'alayhi wa sallam used to deliver his sermon with this opening:
"
The best word is the Book of Allâh and the best way is that of Muhammad ( !). The worst deed is innovation and each innovation is a deviation from Islaam." [Sahih Muslim: (vol. 2, p. 410, no. 1885).]
There is an additional remark in Sunan An-Nasaaee:
"
Every deviation from Islaam leads to Hell-fire". [Sunan Nasa’i: English Translation: (vol. 2, pp. 343-4, no. 1581.)]
‘Aayshah reported that the Prophet sallallaahu 'alayhi wa sallam said: "
Whoever does an act which is not in agreement with our faith, such an act is rejected." [Sahih Al-Bukhari: (vol. 3, no. 861.).]
There is another report by her with different wordings:
"
Whoever invents something in our faith which does not originally exist, has nothing to do with us." [ Sahih Muslim: (vol. 3, p. 931, nos. 4266-7).]
‘Irbaad ibn Saariyah reported that the Prophet sallallaahu 'alayhi wa sallam said: "
Whoever survives me would observe many differences. However, you should follow my sunnah and that of my rightly guided caliphs. Adhere to it firmly. Beware! Avoid innovation, for each innovation is a deviation from Islaam." [Sunan Abu Dawud: (vol. 3, p. 1294, no. 4590).]
