Sayyiduna Ja'dah (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) saw a man with a large belly, and, pointing his fingers into his belly, he said: "If this were somewhere other than this, it would have been better for you."
In one narration it is stated that a man saw a dream concerning the Prophet (peace and blessings be upon him). So he (peace and blessings be upon him) sent for him. When he came, he related his dream to him (peace and blessings be upon him). That man had a large belly (he was fat), so he (peace and blessings be upon him), pointing at (or touching) his belly with his blessed finger, said: "If this (flesh/fat) were somewhere other than this place (for example, in jihad in the path of Allah and the like), it would have been better for you."
Al-Tabarani (may Allah have mercy on him) recorded the whole of this report, and Ahmad (may Allah have mercy on him) also narrated it, except that in his narration it is the Prophet (peace and blessings be upon him) himself who saw the dream about that man. The narrators of all the chains are the narrators of Sahih al-Bukhari and Muslim, except for Abu Isra'il al-Jushami, and he too is thiqah (trustworthy).
