3 verses have
days
in Edition Clear Qur'an by Talal Itani / Aal-i-Imraan (The Family of Imraan)

3:24That is because they said, “The Fire will not touch us except for a limited number of days.” They have been misled in their religion by the lies they fabricated.

3:41He said, “My Lord, give me a sign.” He said, “Your sign is that you shall not speak to the people for three days, except by gestures. And remember your Lord much, and praise in the evening and the morning.”

3:140If a wound afflicts you, a similar wound has afflicted the others. Such days We alternate between the people, that God may know those who believe, and take martyrs from among you. God does not love the evildoers.
