Abu Huraira reported Allah's Messenger ﷺ as saying

When one of you recites, "By the fig and the olive”1 and comes to "Is not Allah the best of judges?”2 he should say, "Certainly, and I am one of those who testify to that.” When one recites, "I swear by the day of resurrection”3 and comes to "Is not that One able to raise the dead to life?’4 he should say, "Certainly.” And when one recites, "By those that are sent”5 and comes to "Then in what message after that will they believe?”6 he should say, "We believe in Allah.” 1. Al-Qur’an; 95 2. Verse 8 3. Al-Qur’an; 75 4. Verse 40. 5. Al-Qur’an; 77 6. Verse 50. Abu Dawud transmitted it, and Tirmidhi transmitted up to "and I am one of those who testify to that.”
