Sulayman bin Yasar (may Allah have mercy on him) says that the Messenger of Allah (peace and blessings be upon him) used to send Abdullah bin Rawahah (may Allah be pleased with him), and he would make the estimate between him and the Jews. Then they gathered for him some of their women's jewellery and said: This is for you; lighten it for us and overlook (some) in the division. Abdullah bin Rawahah (may Allah be pleased with him) said: O community of Jews! By Allah, you are among the most hateful of Allah's creation to me, yet that will not lead me to wrong you. As for the bribe you have offered, it is unlawful, and we do not consume it. They said: By this (justice) the heavens and the earth stand firm.
