Ramzan Fasting starts History
People of the Quraish Tribe in Mecca (Saudia Arabia) used to observe fast in the days of Jahalia (before Islam) on 10th of Ashoor. They treated Ashoor as sacred untill the ramzan fasting month became obligatory.
The Quraish had the duty to take care of pilgrims. On the day of Ashoor the Kaaba cloth used to change.
The Holy Prophet Muhammad observed the Ashoor fast on the 10th Muharram.
In the 5th of Nabvi, Hazrat Jaafar made the speech before the King Najashi of Syria. Hazrat Jaafar mentioned of the fasting in his speech. It shows the companions of the Prophet also used to observe Ashoor fast.
when the Holy Prophet Muhammad came to Madina in Saudia Arabia, He came to know that the Jews observe fast on the Ashoor day. When he inquired the reason, it came to limelight, that Jews used to fast on the ashoo. The Jews believed that the Prophet Moses got relieved from the King Faroon on the Ashoor day.
The Holy Prophet Muhammad said that the Muslims ows more to the Prophet Moses than the Jews do. So, He continued fasting on the Ashoor day.
Ramzan fasting became obligatory in the 2nd Hijrah. And the Ashoor fast left optional. However, the Holy Prophet Muhammad kept on fasting on the Ashoor day.
