(And verily We created the heavens and the earth, and all that is between them, in six Days, and naught of weariness touched Us) [50:38].
Al-Hasan and Qatadah said: “The Jews said: ‘Allah created the creation in six days and rested on the seventh, Saturday’, which they call the Sabbath, and so Allah, exalted is He, revealed this verse”.
Ahmad ibn Muhammad al-Tamimi informed us> ‘Abd Allah ibn Muhammad ibn Ja‘far al-Hafiz> Ibrahim ibn Muhammad ibn al-Hasan> Hannad ibn al-Sari> Abu Bakr ibn ‘Ayyash> Abu Sa‘d al-Baqqal> ‘Ikrimah> Ibn ‘Abbas who said: “The Jews came to the Prophet, Allah bless him and give him peace, and asked him about the creation of the heavens and earth. He said to them: ‘Allah created the earth on Sunday and Monday; He created the mountains [and what they contain of benefits] on Tuesday; He created the trees and water on Wednesday; He created heaven on Thursday; on Friday, He created the stars, sun and moon’. ‘And what after that, O Muhammad?’ the Jews asked. He said: ‘Then, He established Himself on the Throne’. They said: ‘You would have answered correctly, if you added: and then He rested’. The Messenger of Allah, Allah bless him and give him peace, was furious. This verse was then revealed (And verily We created the heavens and the earth, and all that is between them, in six Days, and naught of weariness touched Us. Therefor (O Muhammad) bear with what they say) [50:38-39]”.
