يُوشِكُ الْأُمَمُ أَنْ تَدَاعَى عَلَيْكُمْ كَمَا تَدَاعَى الْأَكَلَةُ إِلَى قَصْعَتِهَا، فَقَالَ قَائِلٌ: وَمِنْ قِلَّةٍ نَحْنُ يَوْمَئِذٍ؟ قَالَ: بَلْ أَنْتُمْ يَوْمَئِذٍ كَثِيرٌ، وَلَكِنَّكُمْ غُثَاءٌ كَغُثَاءِ السَّيْلِ، وَلَيَنْزِعَنَّ اللَّهُ مِنْ صُدُورِ عَدُوِّكُمُ الْمَهَابَةَ مِنْكُمْ، وَلَيَقْذِفَنَّ فِي قُلُوبِكُمُ الْوَهْنَ، قَالَ قَائِلٌ: يَا رَسُولَ اللَّهِ، وَمَا الْوَهْنُ؟ قَالَ: حُبُّ الدُّنْيَا وَكَرَاهِيَةُ الْمَوْتِ
Translation: Nations may gather against you as diners gather around a dish. Asked whether Muslims would be few, he replied that they would be numerous yet like the froth of a flood. Their opponents’ awe of them would be removed, and wahn would be cast into their hearts. Asked what wahn was, he answered: love of worldly life and aversion to death.

تَدَاعَى عَلَيْكُمْ pictures people calling one another to gather against you. الْأَكَلَةُ means diners, and قَصْعَةٌ is a large shared dish. The image conveys vulnerability before a concerted gathering.
Asked whether the community would be few, the reply was بَلْ أَنْتُمْ يَوْمَئِذٍ كَثِيرٌ: it would be numerous. The weakness described is therefore not explained by numbers alone.
