قَالَ ٱللَّهُ إِنِّي مُنَزِّلُهَا عَلَيۡكُمۡۖ فَمَن يَكۡفُرۡ بَعۡدُ مِنكُمۡ فَإِنِّيٓ أُعَذِّبُهُۥ عَذَابٗا لَّآ أُعَذِّبُهُۥٓ أَحَدٗا مِّنَ ٱلۡعَٰلَمِينَ ١١٥
Allāh said, "Indeed, I will send it down to you, but whoever disbelieves afterwards from among you - then indeed will I punish him with a punishment by which I have not punished anyone among the worlds."
Translation: Saheeh International (English)
Each word's meaning and sound
Allah answered the prayer of Jesus (peace be upon him) and said that He would send down the table that they had requested. He also told him that if anyone disbelieves after the table is sent down then they should blame only themselves, and that Allah will punish them with a severe punishment, unlike any other: due to them seeing an overwhelming proof and any denial being the result of stubbornness. Allah fulfilled His promise and sent down the table to them.
