Quatre choses sont vaines à faire

4-143 Muhammad ibn Ali ibn ash-Shah narrated that Abu Hamid quoted Abu Yazid Ahmad ibn Khalid al-Khalidy, on the authority of Muhammad ibn Ahmad ibn Salih al-Tamimy, on the authority of his father, on the authority of Muhammad ibn Hatam al-Qat’tan, on the authority of Hammad ibn Amr, on the authority of Ja’far ibn Muhammad as-Sadiq (MGB), on the authority of his father (MGB), on the authority of his grandfather (MGB), on the authority of Ali ibn Abi Talib (MGB) that the Prophet (MGB) in his will to Ali (MGB) said, “O Ali! Four things are done in vain: eating after (attaining) satiety; lighting a lamp in moonlight; planting seeds in salty ground; and doing a favor for people who are not worthy of it.”

...qu'il a dit dans son testament à Ali: "Ô Ali, il y a quatre choses qui éloignent le malheur : manger après avoir atteint la satiété, allumer une lampe en pleine lune, semer dans un marais et fabriquer quelque chose pour quelqu'un qui n'en est pas digne."
