Surah 23. Al-Muminun, Ayah 52

As in 21:92 , the above verse is addressed to all who truly believe in God, whatever their historical denomination. By the preceding reference to all of God's apostles the Qur'an clearly implies that all of them were inspired by, and preached, the same fundamental truths, notwithstanding all the differences in the ritual or the specific laws which they propounded in accordance with the exigencies of the time and the social development of their followers. (See notes [66-68] on the second paragraph of 5:48 .)

Cf. xxi. 92-93. All prophets form one Brotherhood: their message is one, and their religion and teaching are one; they serve the One True God, Who loves and cherishes them; and they owe their duty to Him and Him alone.
