They ask you concerning the new moon. Say: They are times appointed for (the benefit of) men, and (for) the pilgrimage; and it is not righteousness that you should enter the houses at their backs, but righteousness is this that one should guard (against evil); and go into the houses by their doors and be careful (of your duty) to Allah, that you may be successful.

And those who are careful of (their duty to) their Lord shall be conveyed to the garden in companies; until when they come to it, and its doors shall be opened, and the keepers of it shall say to them: Peace be on you, you shall be happy; therefore enter it to abide.
