Musannaf Ibn Abi Shaybah 22939 — The "ten for twelve" sale

Sa'id bin Jubayr (may Allah have mercy on him) disliked the sale of ten for eleven and ten for twelve. The narrator said: I asked: Then how should I do it? He (may Allah have mercy on him) said: Say: I took it for such an amount, and I am selling it to you for such and such an amount.
