(Lo! In the creation of the heavens and the earth…) [3:190].
Abu Ishaq al-Muqri’ informed us> ‘Abd Allah ibn Hamid> Ahmad ibn Muhammad ibn Yahya al-'Anbari> Ahmad ibn Najdah> Yahya ibn ‘Abd al-Hamid al-Humani> Ya‘qub al-Qummi Ja‘far ibn Abi al-Mughirah> Sa‘id ibn Jubayr> Ibn ‘Abbas who said: “The people of Quraysh went to the Jews and said: ‘What are the signs that Moses brought to you?’ They replied: ‘His staff and white hand for people to see’. Then they went to the Christians and said: ‘How was Jesus in your midst?’ They said: ‘He restored eyesight to the blind, healed the leper and brought the dead back to life’. The people of Quraysh then went to the Prophet, Allah bless him and give him peace, and said: ‘Ask your Lord to turn the hill of al-Safa into gold’. As a consequence, Allah, exalted is He, revealed (Lo! In the creation of the heavens and the earth and (in) the difference of night and day are tokens (of His Sovereignty) for men of understanding)”.
