Riyad as-Saliheen 1887
Abu Sa'id Al-Khudri (May Allah be pleased with him) said:
The Prophet ﷺ said, "The dwellers of Jannah will look at those in the upper abodes above them as you look at a shining star which remains in the eastern or western horizon; such will be the difference in superiority which some of them have over others." The Messenger of Allah ﷺ was asked: "Will those be the dwellings of the Prophets which no one else will be able to reach?" He ﷺ replied, "Yes, but by Him in Whose Hand my soul is! men who believed in Allah and acknowledged the truthfulness of the Messengers will reach them."
[Al-Bukhari and Muslim].
وعنه عن النبي ﷺ قال: "إن أهل الجنة ليتراءون أهل الغرف من فوقهم كما تراءون الكوكب الدري الغابر في الأفق من المشرق أو المغرب لتفاضل ملا بينهم" قالوا: يا رسول الله، تلك منازل الأنبياء لا يبلغها غيرهم؟ قال: “بلى والذي نفسي بيده رجال آمنوا بالله وصدقوا المرسلين" ((متفق عليه)).
