Shiavault - a Vault of Shia Islamic Books An Enlightening Commentary into the Light of the Holy Qur'an vol.
"They ask you concerning the new moons; say: 'They are times appointed for mankind and (for) the Hajj'.
It is not righteousness that you should enter dwellings from their backs but righteousness is this that one should guard himself (against evil); and enter the dwellings by their (proper) doors, and fear Allah: that you may be prosperous." Occasion of Revelation It has been said that Ma'az-ibn-Jabal came to the Prophet (S) and said that he was frequently asked about the crescent of the moon and that why it gradually changes to a full shape and then alters to its first status.
Also, it is narrated that the Jews asked the Messenger of Allah (S) what the crescent of the moon was for and what the use of it was. At that time the above verse was sent down and announced that the different states of the moon have different material and spiritual advantages in the system of the human beings' lives.
As mentioned in the occasion of revelation of the verse, some people asked the Prophet of Islam (S) a few questions about the reason of the different peculiar shapes that the Moon seemed to have and the concerning use of them. In answer to these questions, Allah ordered the Prophet (S) to tell them the effects and the different usages of the crescent for all people. They ask you concerning the new moons; say: 'They are times appointed for mankind and (for) the Hajj'.
