Abu Saeed reported that the Prophet said, ‘There are one hundred levels in Paradise. If all people were gathered in any one of them, it would be spacious enough to contain them.’ Abu Isa described this hadith as gharīb.

The Arabic says ‘the worlds/people’ (al-ʿālamīn); the English witness interprets this as all the inhabitants of Paradise. The translation retains the broader wording without specifying further.
