Surah 17. Al-Israa, Ayah 19

Since caring and striving for the good of the hereafter presupposes belief in God and in man's responsibility before Him, it is obvious that the term "believer" relates, in this context, to a cognition of God's absolute oneness and uniqueness as well as to a willing acceptance of the guidance offered to man through prophetic revelation. - In the original, the whole preceding sentence has the singular form ("he who cares...and strives...and is a believer"); but in view of the next clause, which is expressed in the plural, it is preferable to render these pronouns, agreeably with Arabic usage, uniformly in the plural.

This is in contrast to the last verse. Those who wish for mere earthly good sometimes get it and misuse it. Those whose eyes are fixed on the Hereafter, they too share in their Lord's bounty provided they fulfil the conditions explained in the next note; but their wishes and endeavours are more acceptable in the sight of Allah.

A mere wish for moral and spiritual good is not enough. It must be backed up by hard endeavour and supported by a lively Faith. On those conditions the wishes are accepted by Allah.
