It is narrated from Sayyiduna Amr bin Hurayth (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) passed by Sayyiduna Abdullah bin Ja'far (may Allah be pleased with him) while he was busy buying and selling with the boys — or he said, the children — so he (peace and blessings be upon him) supplicated for him, saying: 'Allahumma barik lahu fi bay'ihi (or he said: fi safqatihi)' (O Allah, bless him in his trade — or he (peace and blessings be upon him) said — in his deal).
