Just a final note, according to Muzammil Siddiqui, who is a really well respected scholar, he says there is nothing in Islam to prevent anyone from having a wedding in Muharram, even in the first ten days. Culturally, we don't do it in the first ten days, but that's an innovation. If there was some pressing reason to do it in Muharram, there is no gunah on you.
aik dum right :)
