Reply to Barakallahu Feek (Invocation for someone who tells you: May Allah bless you)

Aaishah reported that the Messenger of Allah was given a sheep and he ordered for it’s distribution. When the servant would come back from distributing it, ʿAishah would ask: ‘What did they say?’, he replied: They would supplicate: May Allah bless you all. ʿAishah would then say:

Wa fīka bāraka llāh

and may Allah bless them.
