The Thunder
In the name of God, Most Gracious, Most Merciful.
[13:36]
Those to whom We have given the Book rejoice at what hath been revealed unto thee: but there are among the clans those who reject a part thereof. Say: "I am commanded to worship God, and not to join partners with Him. Unto Him do I call, and unto Him is my return."


* v.36 : The Book: in a general sense, Revelation. "Those to whom the Book hath been given" are both (1) the People of the Book of previous revelations, who study the new Revelation in Arabic without prejudice and find in it confirmation of what their ancestors had received and believed in it, and (2) the Muslims who receive the Qur-An with such joy.
* Ahzab (plural of hizb = parties, sects, troops, clans. The reference may be to the clans mentioned in xxx. 20 and 22 (that whole Sura is called Ahzab). But we can understand it in a perfectly general sense. Among all sections of the people there are persons who would receive a portion of Allah’s truth but reject whatever does not suit them or fall in with their selfish aims or vain desires. The proper answer to them is: Surely, Allah’s command is universal,-to worship and serve Him and refuse to bend the knee to any other; the man of God finds his staff and support in it; but he must invite all to share in its blessings; it came from Allah, and to Allah shall we all return.
