﴿ وَشَاهِدٍۢ وَمَشْهُودٍۢ ﴾

“and [of] Him who witnesses [all], and [of] that unto which witness is borne [by Him]!”

(And by the witness) the day of Friday (and that whereunto he beareth testimony) the day of 'Arafah and it is said it is the day of immolation; it is also said that 'the witness' refers to the children of Adam while 'that whereunto he bears testimony' refers to the Day of Judgement; and it is also said that 'the witness' is Muhammad (pbuh) while 'that whereunto he bears testimony' is his community; Allah swore by all these things that His chastisement of those who disbelieve in Him is very severe,
