“why”
in Edition Clear Qur'an by Talal Itani / Al-A'raaf (The Heights)
7:93So he turned away from them, and said, “O my people, I have delivered to you the messages of my Lord, and I have advised you, so why should I grieve over a disbelieving people?”
7:164And when a group of them said, “Why do you counsel a people whom God will annihilate, or punish with a severe punishment?” They said, “As an excuse to your Lord, and so that they may become righteous.”
7:203If you do not produce a miracle for them, they say, “Why don’t you improvise one.” Say, “I only follow what is inspired to me from my Lord.” These are insights from your Lord, and guidance, and mercy, for a people who believe.

Those who spend their wealth by night and day, privately and publicly, will receive their reward from their Lord. They have nothing to fear, nor shall they grieve.
