Hadith: The first group to enter Paradise will be like the full moon on its brightest night, and those who will follow them will be like the brightest shining star in the sky

عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ، قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ:
«إِنَّ أَوَّلَ زُمْرَةٍ يَدْخُلُونَ الجَنَّةَ عَلَى صُورَةِ القَمَرِ لَيْلَةَ البَدْرِ، ثُمَّ الَّذِينَ يَلُونَهُمْ عَلَى أَشَدِّ كَوْكَبٍ دُرِّيٍّ فِي السَّمَاءِ إِضَاءَةً، لاَ يَبُولُونَ وَلاَ يَتَغَوَّطُونَ، وَلاَ يَتْفِلُونَ وَلاَ يَمْتَخِطُونَ، أَمْشَاطُهُمُ الذَّهَبُ، وَرَشْحُهُمُ المِسْكُ، وَمَجَامِرُهُمْ الأَلُوَّةُ الأَنْجُوجُ، عُودُ الطِّيبِ وَأَزْوَاجُهُمُ الحُورُ العِينُ، عَلَى خَلْقِ رَجُلٍ وَاحِدٍ، عَلَى صُورَةِ أَبِيهِمْ آدَمَ، سِتُّونَ ذِرَاعًا فِي السَّمَاءِ».

Abu Hurayrah (may Allah be pleased with him) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) said:
"The first group to enter Paradise will be like the full moon on its brightest night, and those who will follow them will be like the brightest shining star in the sky. They will not urinate, defecate, spit, or blow their noses. Their combs will be of gold, and their sweat will smell like musk. Their censers will be the aloes-wood and their wives will be the houris. All of them will look alike and will resemble their father Adam, sixty cubits tall."
[Authentic hadith] - [Narrated by Bukhari & Muslim] - [Sahih Bukhari - 3327]

Explanation

The Prophet (may Allah's peace and blessings be upon him) informed that the first group of believers to enter Paradise will have faces that shine like the full moon on its brightest night, followed by those who are as radiant as the most luminous stars in the sky. They will have attributes of perfection, as they will not urinate, defecate, spit, or blow their noses. Their combs will be made of gold, their sweat will smell like musk, and their incense burners will emit the finest fragrances. Their spouses will be the houris, and they will be created with a unified appearance, resembling their father Adam in form and height—sixty cubits tall in stature.
