Allah said,
<Whosoever intercedes for a good cause, will have the reward thereof;>
meaning, whoever intercedes in a matter that produces good results, will acquire a share in that good.
<And whosoever intercedes for an evil cause, will have a share in its burden.>
meaning, he will carry a burden due to what resulted from his intercession and intention. For instance, it is recorded in the Sahih that the Prophet said,
«Intercede and you will gain a reward of it. Yet, Allah shall decide whatever He wills by the words of His Prophet.»
Mujahid bin Jabr said, “This Ayah was revealed about the intercession of people on behalf of each other.” Allah then said.
<And Allah is Ever Muqit over everything.>
Ibn ‘Abbas, ‘Ata’, ‘Atiyah, Qatadah and Matar Al-Warraq said that,
<Muqit> means, “Watcher.” Mujahid said that Muqit means, Witness', and in another narration, 'Able to do.'
