((وَفِيكَ بَارَكَ اللَّهُ)).
(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), AAaishah would ask: ‘What did they say?’, he replied: They would supplicate: (May Allah bless you all.) AAaishah would then say: (and may Allah bless them.))(we return their supplication in a similar way and our reward remains with us.)
