"And remind them of the days of Allah." According to the interpretation of al-Kalbi: Remind them of Allah's blessings upon them, and remind them (f. 164) of how He destroyed the people of Noah, Ad, Thamud, and others. He says: Remind them of this and that. "Indeed, in that are signs for every patient, grateful one." And he is the believer.
