I have never heard the Prophet ﷺ saying about anybody walking on the earth that he is from the people of Paradise except ʿAbdullah bin Salam. The following Verse was revealed concerning him: "And a witness from the children of Israel testifies that this Qur'an is true" (46.10)
سَمِعْتُ النَّبِيَّ ﷺ يَقُولُ لأَحَدٍ يَمْشِي عَلَى الأَرْضِ إِنَّهُ مِنْ أَهْلِ الْجَنَّةِ إِلاَّ لِعَبْدِ اللَّهِ بْنِ سَلاَمٍ قَالَ وَفِيهِ نَزَلَتْ هَذِهِ الآيَةُ {وَشَهِدَ شَاهِدٌ مِنْ بَنِي إِسْرَائِيلَ} الآيَةَ قَالَ لاَ أَدْرِي قَالَ مَالِكٌ الآيَةَ أَوْ فِي الْحَدِيثِ
