Except those [poets] who believe and do righteous deeds and remember Allāh often and defend [the Muslims]1 after they were wronged. And those who have wronged are going to know to what [kind of] return they will be returned.
Translation: Saheeh International (English)
1 By replying through poetry to the attacks of hostile poets.
Except for those poets who have faith, perform good deeds, remember Allah abundantly and take retribution from the enemies of Allah after they have oppressed, like Hassān bin Thābit may Allah be pleased with him. Those who committed wrong by ascribing partners to Allah and showing hostility to His servants, will soon know what their place of return will be: they will return to a great place and a meticulous accounting.
