Is selling and buying permissible inside a mosque?

Primary text

Selling and buying inside the mosque is disliked (makruh). Ishaq held this view. The evidence is the narration from Abu Hurayrah where the Messenger of Allah, peace be upon him, said: "If you see someone selling or buying in the mosque, say: 'May Allah not profit your trade,' and if you see someone announcing a lost item in the mosque, say: 'May Allah not return it to you.'" This hadith was reported by Al-Tirmidhi and deemed Hasan Gharib. Furthermore, mosques were not established for this purpose. Imran Al-Qasir saw a man selling in the mosque and stated: "This is the marketplace of the Hereafter; if you desire trade, go out to the marketplace of this world."
