Ramadhan
This maybe late, but..
I think, it is our right to tell people(friends, family even strangers).
What is Ramadan?
The 9th month of the Islamic calendar, which is based on the orbiting of the moon (lunar calendar), rather than the orbiting of the earth (solar calendar). It was in the month of Ramadan in which the Quran (Our Holy Book) was first revealed.
What is Fasting?
We(the Muslims) will hold, and no substitute should be introduced into the body, which could be considered as providing nourishment to the body. Fasting also involves abstaining from evil intentions and desires.
This might be a short post, but I just feel like to spread it.
JazakAllahukhair.
