﴿ﺇِﻥَّ ﺍﻹِﻧﺴَـﻦَ ﻟِﺮَﺑِّﻪِ ﻟَﻜَﻨُﻮﺩٌ ﴾

(Verily, man is ungrateful (Kanud) to his Lord.)

This is the subject what is being sworn about, and it means that he (man) is ungrateful for the favors of His Lord and he rejects them.

bin Anas and Ibn Zayd all said, "Al-Kanud means ungrateful.''

Al-Hasan said, "Al-Kanud is the one who counts the
calamities (that befall him) and he forgets Allah's favors.''
