What cuts of beef will I find in a halal market?

Halal has not restrictions when comes to the cuts after the animal is slaughter in the Halal manner, Kosher does when it comes to beef, but not other animals, so for a nice roast look at a sirloin one, top, bottom or tip, tri-tip is nice to, slow roast it, and season it as you normally would

The rules regarding halal meat in Islam pertain ONLY to the slaughtering process, not the butchering. Once an animal has been slaughtered according to the rules of Islam, the carcass can be butchered and cut up in any way desired. The butchering process can vary quite a bit from culture to culture, with cuts very common in one culture being totally unheard-of in another culture. Outside of traditionally Muslim countries, most halal butchers cater to the local Muslim immigrant communities and the cultures from which they come. For example, if the local Muslim community is mostly from the Middle East, the hala butcher will typically carry a lot of halal beef, along with the usual chicken, lamb/mutton, goat, etc., whereas if the local Muslim community is mostly from South Asia (India, Pakistan, Bangladesh, Sri Lanka) where eating beef is less common, you might not find a large selection of different cuts of halal beef.

Another responder mentioned that certain cuts of beef might not be kosher, and this is why kosher butchers don't carry cuts from the hindquarters of the cow. This is typically what one sees, at least in developed countries, but it's not technically true. Cuts from the hindquarters CAN be kosher...the trick is to remove the sciatic nerve (the large nerve which runs down the entire length of the hind limbs), as the meat directly touching the sciatic nerve is NOT kosher. The delicate process of teasing out the sciatic nerve is time-consuming and requires some skill, which is too labor-intensive for most butchers in developed countries such as the US, UK, the EU, Canada, Australia, etc. It is more cost-effective for kosher butchers in those countries to sell the hindquarters from animals slaughtered according to Jewish law to non-kosher butchers, than it would be to actually cut up the hindquarters in according to Jewish law. This is a technicality that even many Orthodox Jews who have grown up in developed countries do not fully understand, so they have grown up with a sort of aversion to hindquarter cuts, so that even if they were available in their local kosher butcher shop, they would be regarded with suspicion and would not be desirable, since they would not be cuts they have grown up eating nor would they have developed a taste for them.

pretty much the same as those found in supermarkets, i dont know if muslims go for roasts though so that may be a little tricky to get.

any wear halal is muslim who eat beef but not pork and i'm sure there are loads in manchester

The slaughter process is only halaal all cuts are available
