Hadith.3948 - Amr ibn Shimr narrated from Jabir, who reported:
Abu Ja'far Imam Muhammad ibn Ali Al-Baqir (as) was asked about lending meat in advance.
Imam (as) said
"Do not approach it, for sometimes he may give you fat meat, sometimes lean meat, and sometimes emaciated meat. Instead, buy it through direct observation, hand-to-hand."
Imam (as) was also asked about lending water carriers (skins).
Imam (as) said: "No, for sometimes he may give you an incomplete one and sometimes a complete one. Rather, buy them through direct observation, for this is safer for you and for him."
