Re: zam zam mixing
^ ppl bring zam zam as a tabarruk (anything that is ba-barkat), n as i said abt a hadith that jis niyat se piya jaye puri hogi InshaAllah so its mean that its shifa....atleast me n my family bring zam zam with this reason i dont know abt others.
n as in my last sentence abt hadith....i never said abt mix or not i just meant to say it is very special water and y u ppl mix this water with other water n give o others n poor ppl think its all pure as they bring from macca or madina...o poor ppl.
