It is based on the migration of the Prophet Muhammad (s.a.w) from Mecca to Medina in 622 AD.However, the use of the Hijri calendar began in AD 639 or 17 AH during the Khilafat of Syedna Umar Farooq (ra).It was for this reason that the Jews used to fast on this day.
Therefore AD 622 became the 1 AH and since the decision to migrate was made right at the end of the month of Dhul-Hajj, and the first moon to rise after this was that of Muharram, thus Muharram came to be the first month of the Islamic Hijri calendar.
(Fatah Al bari 334/7 Hadith 3934) Junaid Baghdadi has said, “Assess each moment of life by evaluating how close you have come to Allah , and the most excellent prayer after what is prescribed is prayer during the night.” [Muslim 6: 2661] Prophet Muhammad (saw) called Muharram “Allah’s Month” which shows its importance and sanctity and the fasts of the month of Muharram are most reward able ones among the was made optional.
Narrated by Aisha (ra): “The people used to fast on ‘Ashura (the tenth day of the month of Muharram) before the fasting of Ramadan was made obligatory.
And on that day the Ka’ba used to be covered with a cover.
Muharram festival 2019 would be celebrated by the people of Islam religion all over the world on 10th of September Tuesday.
Dates of the celebration may vary according to the place.Whereas, according to the Sunni Muslims, it is the day when Moses got victory over Egyptian Pharaohs.According to the history, it is considered as the Moses was a religious Islam leader, who was propagating the religious teachings among people all around the world.Ibn e Abbas ra narrated: “When the Prophet came to Medina, he found (the Jews) fasting on the day of ‘Ashura’ (i.e. They used to say: “This is a great day on which Allah saved Moses and drowned the folk of Pharaoh.Moses observed the fast on this day, as a sign of gratitude to Allah.” The Prophet said, “I am closer to Moses than they.” So, he observed the fast (on that day) and ordered the Muslims to fast on it.[ Bukhari: Vol 4, Book 055, Hadith Number 609] Ibn ‘Abbas ra reported: ”When the Messenger of Allah (may peace be upon him) fasted on the day of ‘Ashura and commanded that it should be observed as a fast, they (his Companions) said to him: Messenger of Allah, it is a day which the Jews and Christians hold in high esteem.Thereupon the Messenger of Allah (may peace be upon him) said: When the next year comes, God willing, we would observe fast on the 9th But the Messenger of Allah (may peace be upon him) died before the advent of the next year.” [ Musim : Book 006, Hadith Number 2528] Abdullah ibn Abbas (ra) also reported that the Messenger of Allah (may peace be upon him) had said: “If I live till the next (year), I would definitely observe fast on the 9th.[ Muslim: Book 006, Hadith Number 2529] Hence, one should combine another day with the fast of Ashura and fast on either the 9th and 10th of Muharram or the 10th and 11th in order to distinguish the Muslim way of fasting from that of the Jews.And he got victory on the tenth day of the Muharram over the Pharaohs of Egypt.Both factions of the Muslim community celebrate this day with almost identical traditions. It is one of the four sacred months during which waging a war and fighting is not allowed.Allah says in the Holy Quran: “Surely the number of months with Allah is twelve months in Allah’s ordinance since the day when He created the heavens and the earth, of these four being sacred; that is the right reckoning; therefore be not unjust to yourselves regarding them.”[Surah 9 : At-Taubah, Verse 36] Prophet Muhammad (saw) informed us about the four sacred months in the following narration: “The year is of twelve months, out of which four months are sacred: Three are in succession Dhul-Qa’ da, Dhul-Hijja and Muharram, and (the fourth is) Rajab…” [Bukhari Vol 004, Book 054, Hadith 419 Muharram is the first month of the Islamic Hijri calendar.
