The Religion of the Messengers is One
Allah says to this Ummah:
شرع لكم من الدين ما وصى به نوحا والذي أوحينا إليك
He (Allah) has ordained for you the same religion which He ordained for Nuh, and that which We have revealed to you,
Allah mentions the first Messenger who was sent after Adam, that is, Nuh, peace be upon them, and the last of them is Muhammad.
وما وصينا به إبراهيم وموسى وعيسى
and that which We ordained for Ibrahim, Musa and Isa,
Then He mentions those who came in between them who were the Messengers of strong will, namely Ibrahim, Musa and Isa bin Maryam. This Ayah mentions all five, just as they are also mentioned in the Ayah in Surah Al-Ahzab, where Allah says:
وإذ أخذنا من النبيين ميثاقهم ومنك ومن نوح وإبرهيم وموسى وعيسى ابن مريم
And (remember) when We took from the Prophets their covenant, and from you, and from Nuh, Ibrahim, Musa, and Isa son of Maryam. (33:7)
The Message which all the Messengers brought was to worship Allah Alone, with no partner or associate, as Allah says:
وما أرسلنا من قبلك من رسول إﻻ نوحى إليه أنه ﻻ إله إﻻ أنا فاعبدون
And We did not send any Messenger before you but We revealed to him (saying): None has the right to be worshipped but I, so worship Me. (21:25).
And according to a Hadith (the Prophet said):
نحن معشر اﻻنبياء أوﻻد عﻼت ديننا واحد
We Prophets are brothers and our religion is one.
In other words, the common bond between them is that Allah Alone is to be worshipped, with no partner or associate, even though their laws and ways may differ, as Allah says
لكل جعلنا منكم شرعة ومنهجا
To each among you, We have prescribed a law and a clear way. (5:48)
Allah says here:
أن أقيموا الدين وﻻ تتفرقوا فيه
saying you should establish religion and make no divisions in it.
meaning, Allah enjoined all the Prophets (peace and blessings of Allah be upon them all) to be as one and He forbade them to differ and be divided.
كبر على المشركين ما تدعوهم إليه
Intolerable for the idolators is that to which you call them.
means, `it is too much for them to bear, and they hate that to which you call them, O Muhammad, i.e., Tawhid.'
الله يجتبي إليه من يشاء ويهدي إليه من ينيب
Allah chooses for Himself whom He wills, and guides unto Himself who turns to Him in repentance.
means, He is the One Who decrees guidance for those who deserve it, and decrees misguidance for those who prefer it to the right path.
Allah says here;
