Is it permissible to buy meat sold in Arab stores in northern Europe that is labeled "halal," despite doubts about the method of slaughter and the excessive bleeding from it?

There is no harm in benefiting from meat that has traces of blood in its veins, and no attention should be paid to doubts. The presence of blood in the veins is pardoned, and its consumption is not forbidden. Ibn Jurayj said: "There is no harm in what is in its veins." The mere presence of traces of blood in the meat is not evidence that the animal was not properly slaughtered.
