Ishaaq bin Ebrahim (rahimahullah) narrates the following incident:

On one occasion, Juwain, the neighbor of Imaam Ahmed (rahimahullah), sent a platter of walnuts, raisins and figs to Imaam Ahmed (rahimahullah) as a gift. The value of this gift was not more than three dirhams (silver coins).

On receiving the gift, Imaam Ahmed (rahimahullah) handed me one dinar (gold coin) and instructed, “Go and buy sugar for ten dirhams, and dates for seven dirhams. Take it to the house of Juwain in the evening and present it to him as a gift from my side.”

Accordingly, I fulfilled the instruction of Imaam Ahmed (rahimahullah) and delivered the gift in the evening.
