Allah said,
﴿الْيَوْمَ أَكْمَلْتُ لَكُمْ دِينَكُمْ
وَأَتْمَمْتُ عَلَيْكُمْ نِعْمَتِى وَرَضِيتُ لَكُمُ الأِسْلاَمَ دِيناً﴾
(This day, I have perfected your religion for you, completed My favor upon you,
and have chosen for you Islam as your religion.) This, indeed, is the biggest favor
from Allah to this Ummah, for He has completed their religion for them, and they,
thus, do not need any other religion or any other Prophet except Muhammad . This
is why Allah made Muhammad the Final Prophet and sent him to all humans and Jinn.
Therefore, the permissible is what he allows, the impermissible is what he prohibits,
the Law is what he legislates and everything that he conveys is true and authentic
and does not contain lies or contradictions. Allah said;
﴿وَتَمَّتْ كَلِمَةُ رَبِّكَ صِدْقاً
وَعَدْلاً﴾
(And the Word of your Lord has been fulfilled in truth and in justice,) meaning,
it is true in what it conveys and just in what it commands and forbids. When Allah
completed the religion for Muslims, His favor became complete for them as well.
Allah said,
﴿الْيَوْمَ أَكْمَلْتُ لَكُمْ دِينَكُمْ
وَأَتْمَمْتُ عَلَيْكُمْ نِعْمَتِى وَرَضِيتُ لَكُمُ الأِسْلاَمَ دِيناً﴾
(This day, I have perfected your religion for you, completed My favor upon you,
and have chosen for you Islam as your religion.) meaning, accept Islam for yourselves,
for it is the religion that Allah likes and which He chose for you, and it is that
with which He sent the best of the honorable Messengers and the most glorious of
His Books. Ibn Jarir recorded that Harun bin `Antarah said that his father said,
"When the Ayah,
﴿الْيَوْمَ أَكْمَلْتُ لَكُمْ دِينَكُمْ﴾
(This day, I have perfected your religion for you...) was revealed, during the great
day of Hajj (the Day of `Arafah, the ninth day of Dhul-Hijjah) `Umar cried. The
Prophet said, `What makes you cry' He said, `What made me cry is that our religion
is being perfected for us. Now it is perfect, nothing is perfect, but it is bound
to deteriorate.' The Prophet said,
«صَدَقْت»
(You have said the truth.)'' What supports the meaning of this Hadith is the authentic
Hadith,
«إِنَّ الْإِسْلَامَ بَدَأَ غَرِيبًا،
وَسَيَعُودُ غَرِيبًا، فَطُوبَى لِلْغُرَبَاء»
(Islam was strange in its beginning and will return strange once more. Therefore,
Tuba for the strangers.) Imam Ahmad recorded that Tariq bin Shihab said, "A Jewish
man said to `Umar bin Al-Khattab, `O Leader of the Believers! There is a verse in
your Book, which is read by all of you (Muslims), and had it been revealed to us,
we would have taken that day (on which it was revealed) as a day of celebration.'
`Umar bin Al-Khattab asked, `Which is that verse' The Jew replied, s
﴿الْيَوْمَ أَكْمَلْتُ لَكُمْ دِينَكُمْ
وَأَتْمَمْتُ عَلَيْكُمْ نِعْمَتِى﴾
(This day, I have perfected your religion for you, completed My favor upon you...)
`Umar replied, `By Allah! I know when and where this verse was revealed to Allah's
Messenger . It was the evening on the Day of `Arafah on a Friday.''' Al-Bukhari
recorded this Hadith through Al-Hasan bin As-Sabbah from Ja`far bin `Awn. Muslim,
At-Tirmidhi and An-Nasa'i also recorded this Hadith. In the narration collected
by Al-Bukhari in the book of Tafsir, through Tariq, he said, "The Jews said to `Umar,
`By Allah! There is a verse that is read by all of you (Muslims), and had it been
revealed to us, we would have taken that day (on which it was revealed) as a day
of celebration.' `Umar said, `By Allah! I know when and where this verse was revealed
and where the Messenger of Allah was at that time. It was the day of `Arafah, and
I was at `Arafah, by Allah.'' Sufyan (one of the narrators) doubted if Friday was
mentioned in this narration. Sufyan's confusion was either because he was unsure
if his teacher included this statement in the Hadith or not. Otherwise, if it was
because he doubted that the particular day during the Farewell Hajj was a Friday,
it would be a mistake that could not and should not have come from someone like
Sufyan Ath-Thawri. The fact that it was a Friday, is agreed on by the scholars of
Sirah and Fiqh. There are numerous Hadiths that support this fact that are definitely
authentic and of the Mutawatir type. This Hadith was also reported from `Umar through
various chains of narration.
