The Book of the Believer · Hadith 88 (#Ḥadīth #5)
Chapter 3 | The bond that Allah has set amongst the believers
88 - وعن أبي جعفر (ع) قال المؤمن أخو المؤمن لأبيه وأمّه لأنّ الله (جلّ جلاله) خلقَ المؤمنين مِن طين الجِنان وأجرى في صوَرِهم من ريحِ الجنان، فلذلك هم إخوة لأبٍ وأُم.
88. It has been reported that Abu Ja'far said: Believers are full brothers. That is because Allah [M.G] created the believers from the earth of Paradise and brought about their forms from the breeze of Paradise. For that reason, they are full brothers.
