It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Do not hate one another, do not envy one another, do not turn your backs on one another; none of you should bargain over the bargain of his brother; no emigrant (muhajir) should sell on behalf of a Bedouin; leave the people alone, for Allah Almighty provides for some of them through others; and no woman should stipulate the divorce of her (Muslim) sister."
No one narrated this hadith from Asim (may Allah have mercy on him) except Abu Bakr (may Allah have mercy on him).
