By this sign we understand that the holy phrase Bismillāh-ir-Rahmān-ir-Rahim at the beginning of every Surah belongs to that very Surah and is a part of it. Thus, this holy phrase has not been located as a ceremonial phrase at the beginning of every Surah. 3- The declaration of Barā’at (immunity) was for the infidels’ perjury which has been referred to in verses 7 and 8 of the current Surah.
In Islam, the general law is that promises should be fulfilled, and as long as the opposite party is faithful to the treaty, it should be kept, too. Moreover, in that circumstance, it was for the reason of their weakness that the Muslims had to accept that treaty, else, the desire of the Muslims was the destruction of idolism as rapidly as possible.
Some Details Upon These Verses In the eighth year A.H., Mecca was conquered, but the pagans still continued coming into Meccan to perform their worshipping rites which was, of course, a mixture of superstitions and aberrations. Among their customs it was seen that they used to give in charity the clothing with which they had circumambulated.
Once it happened that a woman desired to perform some more circumambulations after finishing her first circumambulation, but, since she had no more clothes with her, she had to circumambulate nakedly while people were watching her. That circumstance was not tolerable for the Prophet (S) and the Muslims, who were in a very high degree of power. The Prophet (S) was waiting for the command of Allah until when this Surah was revealed in Medina.
The Messenger of Allah (S) commissioned Abū-Bakr to convey some verses of it unto the people of Mecca. The Prophet (S) chose him, maybe, for the reason that he was an old man and people were not sensitive to him.
