(41) 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.

(42) Recite that which hath been inspired in thee of the Scripture, and establish worship. Lo! worship preserveth from lewdness and iniquity, but verily remembrance of Allah is more important. And Allah knoweth what ye do.

(46) And no burdened soul can bear another's burden, and if one heavy laden crieth for (help with) his load, naught of it will be lifted even though he (unto whom he crieth) be of kin. Thou warnest only those who fear their Lord in secret, and have established worship. He who groweth (in goodness), groweth only for himself, (he cannot by his merit redeem others). Unto Allah is the journeying.

Dreadful for the idolaters is that unto which thou callest them. Allah chooseth for Himself whom He will, and guideth unto Himself him who turneth (toward Him).

(49) And those who answer the call of their Lord and establish worship, and whose affairs are a matter of counsel, and who spend of what We have bestowed on them,

(50) Firmly established in the favour of a Mighty King.
