Your wealth and children provide you with a test. (If you maintain balance in this life and the life to come, and take good care of them (2:221)), thus with Allah is a Tremendous Reward
Your wealth and your children are but a trial. It is Allah with Whom is the greatest reward
Dr. Munir Munshey
In reality, your wealth and your children are a trial (for you). There exists with Allah, a tremendous tribute (at the end of the trial)
Dr. Kamal Omar
Surely, what (is a fact is that) your wealth, and your children (happen to be) a trial, while Allah: with Him (is stored) a great reward (for this world as well as the Hereafter)
Your wealth and children are only objects of trial to you! And with Allah is the great reward.
Al-muntakhab fi tafsir al-Qur'an al-Karim
Indeed your wealth and your progeny are but a trial for testing your inclinations and your beliefs, except that Allah in His heaven's realm has a much greater reward
