And be patient, persevering (in doing good, avoiding mistakes, and against all kinds of persecution you are made to suffer in God’s cause), for surely God never leaves to waste the reward of those devoted to doing good, aware that God is seeing them
Be patient... Indeed, Allah will not allow the rewards of those who do good to be lost.
Sayyed Abbas Sadr-Ameli
And be patient(and steadfast); for verily Allah does not waste the reward of the righteous(ones).
Al-muntakhab fi tafsir al-Qur'an al-Karim
In patience possess you people your souls, therefore, be patient and remember that Allah does not annul, withhold or withdraw the fruit people are entitled to reap from deeds of wisdom and piety
