<p style="text-align: left;">There is no dispute amongst the followers of the Ahlul-bait (peace be upon them) that the Prophets and the Imams are sinless, in such a way that they do not commit what opposes the religion. Our scholars have explained in their books of beliefs the evidences to prove this concept. There is no doubt that the Prophet and the Imam are appointed by Almighty Allah. He has ordered people to follow them. So, if it is possible for them to commit sins, they might order people to do so as well and people have to follow them. So their orders would not be trusted to be from Almighty Allah, and He will not order us to follow somebody who can misguide us. Similarly, they are to be taken by their followers as role models. If they were to commit sins, others will be encouraged to do the same.</p>
If the meat is taken from a Muslim or Muslimsâ€™ market, then one is permitted to sell it and buy it and do so on behalf of others. It is not permissible to buy or sell it if he came to know or two just (Adil) witnessed that the said meat is not slaughtered in accordance to the Sharia. Doubting of some people is not sufficient to consider it as non-Halal meat as long as it is possible to be slaughtered in accordance to the Sharia and it is taken from a Muslim or bought from Muslimsâ€™ market.
<p style="text-align: left;">Emulation (taqlīd) is a necessity when a lay believer faces a situation where he does not know the correct religious ruling, as he is supposed to refer to the expert to get the proper answer. Otherwise, without referring to the expert and implementing the ruling, he would be liable for the mistake, whereas he will not be liable when he refers to the expert, even if the latter made a mistake. Taqlīd secures a layperson from liability before the Almighty Allah.</p>
