TAJ-MAHAL is housed with graves,so whosoever views, visits, talks, write or hears about it; out of reverence / obligation to devotedly offer /pray to ALLAH, for all souls to be in peace & ask blessings & Emaan for mankind; else one have no right over it in any form, to comment, enter its precincts, pollute, impure its air & around. Of course, first & foremost one must purify with niyyah too, so that one evades the curse in turn due; failing to abide by these basic norms.
