And on his authority from Ibn 'Abbas, regarding Allah's saying (Praise be to Allah) he said: '(Praise be to Allah) Allah says: gratitude and godhood are Allah's, (Who hath created the heavens) in two days: Sunday and Monday (and the earth) in two days: Tuesday and Wednesday, (and has appointed darkness and light) He created faith and disbelief or night and day. (Yet those who disbelieve) the unbelievers of Mecca (ascribe rivals) idols (unto their Lord).
