Allah tells us that sacrifice and shedding blood in the Name of Allah has been prescribed for all nations. 'Ali bin Abi Talhah reported that Ibn 'Abbas said,

{And for every nation We have appointed religious ceremonies,} "Festivals." 'Ikrimah said, "Sacrifices."

Zayd bin Aslam said, "This means Makkah; Allah did not appoint religious ceremonies anywhere else for any nation."

It was recorded in the Two Sahihs that Anas said, "The Messenger of Allah brought two fat, horned rams; he said Bismillah and Allahu Akbar, then he put his foot on their necks."

Your God is One, even though the Laws of the Prophets may vary and may abrogate one another. All of the Prophets called mankind to worship Allah Alone with no partner or associate.

{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]. Allah says:

{so you must submit to Him Alone.} meaning, submit to His commands and obey Him in all sincerity.

{And give glad tidings to the Mukhbitin.} Mujahid said about Mukhbitin, "Those who find contentment in their faith." Ath-Thawri said, "Those who find contentment in their faith and who accept the decree of Allah and submit to Him." It is better to interpret it by what comes next, which is:

meaning, their hearts fear Him.

{and the patient who bear whatever may befall them} meaning, of afflictions.

{and who perform the Salah,} they fulfill the duties which Allah has enjoined upon them, the duty of performing the obligatory prayers.

the good provision which Allah has given them. They spend on their families and servants, and on the poor and needy; they treat people kindly while remaining within the limits set by Allah. This is in contrast to the hypocrites, who are the opposite of all this, as we have discussed in the Tafsir of Surah Bara'ah; to Allah be praise and blessings.
