Re: Islamic new year
It’s one of the four Holy months which Allah :swt: has declared as holy…And no, it is not holy because Hz. Hassan and Hussain 
were martyred in it…
It is the year the Holy Prophet :saw: did the Hijrah (migration) to Medina and instituted a fast on the 9th and especially the 10th of Muharram…(This is the Sunnah of the Holy Prophet Musa :as:…)
(According to different traditions, you either fast 9th, 10th or 11th, according to some just the 9th or 10th and according to some just the 9th…Most authentic from my knowledge is 9th and 10th…)
It is OK to make Dua and say to other Muslims that may this Year be filled with happiness, peace and prosperity for you and your family…
So I wish you all the same, Ameen…
