Is Islamhelpline.com reliable site? I have read some fatwa in this web site that contradicts with the hadiths.

Answer

Q: We often receive emails on Islamic information through the internet
without knowing the source of the information. Kindly advise if one should
accept such emails or not.
A: There are two aspects: a) The person/s who run the site, b) The
information on the site.
It is of vital importance to know who runs the site. The information being
correct or not is secondary as many people place unanimously-accepted
information to attract visitors and thereafter propagate their incorrect
beliefs and ideologies. Ibn Sireen (RA) advised, ‘Verily this knowledge is
Deen (religion), see from who you get it.’ (Mishkaat pg.37; Qadeemi)

and Allah Ta’ala Knows Best

Mufti Ebrahim Desai
