Hadith 5003
عَنْ عَائِشَةَ قَالَتْ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «الْأَرْوَاحُ جُنُودٌ مُجَنَّدَةٌ فَمَا تَعَارَفَ مِنْهَا ائْتَلَفَ وَمَا تَنَاكَرَ مِنْهَا اخْتَلَفَ» . رَوَاهُ البُخَارِيّ
Aisha (may Allah be pleased with her) narrated: The Messenger of Allah (peace and blessings be upon him) said: "Souls are like recruited troops; those who became familiar with one another (in the world of souls) will be friendly with each other (in this world), and those who felt alienation will remain in disagreement." Narrated by al-Bukhari.
