Question: What is the ruling regarding inviting to organise an Islaamic celebration which the Prophet ﷺ did not celebrate?
Response: Inviting to organise an Islaamic celebration which the Prophet ﷺ did not celebrate, nor his companions (radhi-yAllaahu ‘anhum), is an innovation in the religion and from the causes of excessiveness in the religion of Allaah and legislating that which Allaah has not legislated. It may be that some of these being innovations led to the major shirk (associating partners with Allaah) such as the celebration of the birth[day] of the Prophet ﷺ and the birth[days] of the companions and the scholars. Allaah (Subhaanahu wa Ta’aala) has said:
{Say (O Muhammad to mankind): “If you (really) love Allaah then follow me (i.e. Accept Islaamic Monotheism, follow the Qur.aan and the Sunnah), Allaah will love you and forgive you of your sins. And Allaah is Oft-Forgiving, Most Merciful”}, [Soorah Aal-‘Imraan, Aayah 31].
And He (Subhaanahu wa Ta’aala) said:
{Or have they partners with Allaah (false gods), who have instituted for them a religion which Allaah has not allowed. And had it not been for a decisive Word (gone forth already), the matter would have been judged between them. And verily, for the Zaalimoon (polytheists and wrong-doers), there is a painful torment}, [Soorah ash-Shooraa, Aayah 21].
And He (Subhaanahu wa Ta’aala) said:
{Then We have put you (O Muhammad) on a plain way of (Our) commandment [like the one which We commanded Our Messengers before you (i.e. Legal ways and laws of the Islaamic Monotheism)]. So follow you that (Islaamic Monotheism and its laws), and follow not the desires of those who know not}. [Tafseer at-Tabaree, Vol. 25, Page 146], [Soorah al-Jaathiyah, Aayah 18].
The Prophet ﷺ said:
«Anyone who introduces something into this matter of ours (i.e. Islaam), that which is not from it, will have it rejected» – [the authenticity of] this [narration] is agreed upon [by both Imaam al-Bukhaaree and Imaam Muslim].
And he ﷺ said in his kutbah: «To proceed: Certainly the best speech is the Book of Allaah and the best guidance is the guidance of Muhammad ﷺ and the worst of matters are the newly introduced ones and every innovation is misguidance». Muslim reported it in his Saheeh. The ahaadeeth with this meaning are many.
