It is narrated from Sayyiduna Abdullah bin Salam (may Allah be pleased with him) that he said: "O Messenger of Allah, are we better, or the people who will come after us?" He (peace and blessings be upon him) said: "If one of them were to spend gold equal to (the mountain of) Uhud, he would not reach (the reward of) a single mudd spent by one of you, nor even half of it."
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith is narrated from Sayyiduna Abdullah bin Salam (may Allah be pleased with him) only with this chain; al-Waqidi is alone in narrating it."
"It is like this in the Dar al-Haramayn edition, and it is likewise in the manuscript, as was pointed out in al-Tahhan's edition."
