There is a lesson for you to learn concerning cattle. We provide pleasant milk for you to drink within the delicate system of their veins and arteries. 66 And also a lesson for you in the fruits of the date-palms and the grapes whereof ye take a liquor and a provision goodly; verily therein is a sign far a people who understand. 67 And thy Lord taught the Bee to build its cells in hills, on trees, and in (men's) habitations; 68 Then feed on every kind of fruit, and follow the trodden paths of your Lord." From its belly comes a drink with different colours which provides healing for mankind. Indeed, in this there is a sign for people who give thought. 69 And Allah has created you, then He causes you to die, and of you is he who is brought back to the worst part of life, so that after having knowledge he does not know anything; surely Allah is Knowing, Powerful. 70
