“Wa-in tukhāliṭūhum fa-ikhwānukum”
“If you associate with them, they are your brothers.” (al-Baqarah 2:220, excerpt)
The verse answers a question about dealings with orphans and the management of their affairs. Its conditional response, “they are your brothers,” implies a fuller practical guidance: dealing with them is permissible when done honestly and with the intention of improving their situation.
The conditional does not mean that the physical act of mixing assets creates brotherhood. Rather, brotherhood provides the ethical basis for honorable association and proper care.
This is sentence-level ibdāl: a complete stated clause communicates a further, related practical conclusion.
