Tafseer
'Abdullāh Ibn 'Abbās / Muḥammad al-Fīrūzabādī
تفسير : (and if they behold a portent) like the splitting of the moon (they turn away) they deny the sign (and say:) this sign is nothing but (prolonged illusion) which will vanish.
Jalāl al-Dīn al-Maḥallī
تفسير : and if they, the disbelievers among quraysh, see a sign, a miracle of the prophet (s), they turn away and say, this is: ‘a powerful sorcery!’ (mustamirr, ‘powerful’, derives from al-mirra, meaning ‘strength’; or it [mustamirr] means ‘incessant’).
