Ramadan according to the Qur'an

Imagine if you ask somebody; when Spring comes? He tells you, Spring comes in the Winter! You say; what?! Then he tells you, sometimes it comes in the Summer, or the Summer comes in the Fall! Then you know SOMETHING IS WRONG.

That is what the "Hijri" calendar is doing!

They say at the time they named those months it was Spring or it was Summer! What kind of bad lies is this?! It is like someone called Mr. X. Tailor, because at the time, his great grandfather was sewing a button to his shirt but he was actually a Farmer!

Not only the months rotate around the year in this calendar but they put [Jamad], which means freezing, obviously it is Winter, they put it after Spring! So Winter comes after Spring!

That is not acceptable; add to that, the so called Hijri calendar which supposed to start when the [Hijrah] Migration of the Prophet took place but it is actually starts on [Muharram] even though the Prophet (pbuh) migrated in [Rabee'] the Spring!

Does your day of birth change seasons?! Neither should Laylatu Alqadr!

So, to commemorate something important like Ramadan, we must Fast it at the same time on every year. The Hijri calendar was made after the Prophet (pbuh) without his permission and not according to the Qur'an.
Ramadan is a name of a Month. This Month existed before the revelation of the Qur'an. ALLAH (swt) said:

شهر رمضان الذي إنزل فيه القرءان
The Month of Ramadan in which the Qur'an was sent down....

So they had a Calendar already during the lifetime of our Prophet (pbuh) and if we look closely at the names of its months we can clearly see that they reflect seasons, which means those months are Solar months. So, we will use the Qur'an to construct a Calendar that is pleasing to ALLAH (swt) which is what the Prophet (pbuh) used.

ALLAH (swt) said:
إتبعوا ما أنزل إليكم من ربكم
Follow what was sent down to you from your God.
