الذين قالوا إن الله عهد إلينا أﻻ نومن لرسول حتى يٲتينا بقربان تٲكله النار
Those (Jews) who said: "Verily, Allah has taken our promise not to believe in any Messenger unless he brings to us an offering which the fire (from heaven) shall devour.''
Ibn Abbas and Al-Hasan stated,
Allah refuted their claim that in their Books, Allah took a covenant from them to only believe in the Messenger whose miracles include fire coming down from the sky that consumes the charity offered by a member of the Messenger's nation.
Allah replied,
قل قد جاءكم رسل من قبلي بالبينات
Say: "Verily, there came to you Messengers before me, with Al-Bayinat...''
with proofs and evidence,
وبالذي قلتم
and even with what you speak of,
a fire that consumes the accepted charity, as you asked,
فلم قتلتموهم
why then did you kill them!
Why did you meet these Prophets with denial, defiance, stubbornness and even murder!
إن كنتم صادقين
if you are truthful.
if you follow the truth and obey the Messengers.
Allah then comforts His Prophet Muhammad,
فٳن كذبوك فقد كذب رسل من قبلك جاووا بالبينات والزبر والكتاب المنير
