It is narrated from the Mother of the Believers, Sayyidah Aishah (may Allah be pleased with her), that the Messenger of Allah (peace and blessings be upon him) said: "Give gifts to one another, and mutual love will arise among you; and emigrate, and you will leave a legacy of glory and honour for your children; and overlook the slips of honourable people."
No one narrated this hadith from al-Qasim (may Allah have mercy on him) except Ubaydullah bin al-Ayzar (may Allah have mercy on him), and al-Muthanna Abu Hatim (may Allah have mercy on him) is alone in narrating it.
