Al-Bukhari said: Salih bin Muhammad bin Za'idah Abu Waqid al-Laythi al-Madani was abandoned by Sulayman bin Harb; he is munkar al-hadith (his narrations are denounced). He narrates from Salim, from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both), from Sayyiduna Umar (may Allah be pleased with him), as a marfu' hadith: "Whoever commits breach of trust in the spoils of war, burn his belongings."
(b) Sayyiduna Ibn Abbas (may Allah be pleased with them both) narrated from Sayyiduna Umar (may Allah be pleased with him), from the Prophet (peace and blessings be upon him), about breach of trust in the spoils of war, and he (peace and blessings be upon him) did not burn (the belongings).
Al-Bukhari said: Our companions rely on this regarding breach of trust in the spoils, and that (report of burning) is batil (baseless); it is nothing.
