During Ramadan people are invited to a divine celebration
In the same sermon which was referred to, the Holy Prophet (s.w.a.) said, "This is a month in which you have been invited to a divine celebration". One should think deeply about this sentence. It says that we have been invited to a divine celebration. It is not obligatory for all people to benefit from this divine celebration, no it has been made a faritha. We have the power to choose whether or not to benefit from this celebration. There are some people who do not at all find the opportunity to pay attention to this invitation. They are so ignorant and they pay such careful attention to materialistic issues and the materialistic world that they do not notice when the month of Ramadan arrives and when it ends. They are like the people who are invited to a very impressive and blessed celebration, but they do not have the time to take part in it and they do not even look at the invitation card. These people deprive themselves of all the blessings.
