If ye fulfil the royal law according to the scripture, Thou shalt love thy neighbour as thyself, ye do well: But if ye have respect to persons, ye commit sin, and are convinced of the law as transgressors. For whosoever shall keep the whole law, and yet offend in one point, he is guilty of all.
The way of transgressors is hard.
And We sent after them in their footsteps Jesus, son of Mary, verifying that which was before him of the Torah; and We gave him the Gospel containing guidance and light, and verifying that which was before it of the Torah, and a guidance and an admonition for the dutiful. And let the People of the Gospel judge by that which Allah has revealed in it. And whoever judges not by what Allah has revealed, those are the transgressors.
And what reason have you that you should not eat of that on which Allah's name is mentioned, when He has already made plain to you what He has forbidden to you -- excepting that which you are compelled to. And surely many lead (people) astray by their low desires through ignorance. Surely thy Lord -- He best knows the transgressors.
