(11) And when they entered in the manner which their father had enjoined, it would have naught availed them as against Allah; it was but a need of jacob's soul which he thus satisfied; and lo! he was a lord of knowledge because We had taught him; but most of mankind know not.

(12) Who shall inherit of me and inherit (also) of the house of jacob. And make him, my Lord, acceptable (unto Thee).

(13) So, when he had withdrawn from them and that which they were worshipping beside Allah, We gave him Isaac and jacob. Each of them We made a prophet.

(14) And We bestowed upon him Isaac, and jacob as a grandson. Each of them We made righteous.

(15) And We bestowed on him Isaac and jacob, and We established the prophethood and the Scripture among his seed, and We gave him his reward in the world, and lo! in the Hereafter he verily is among the righteous.

(16) And make mention of Our bondmen, Abraham, Isaac and jacob, men of parts and vision.
