It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him): On the day of the Battle of Yamamah I came to Sayyiduna Thabit bin Qays bin Shammas (may Allah be pleased with him) while he was applying perfume (in preparation for death). I said: O uncle! Do you not see what the people are facing (in the battle)? So he put on his shrouds and went forward, saying: "Now, now (is the time to face them)." And he began rubbing on the perfume, and an Ansari narrator pointed to his shin (to show) that in this way he began clashing with the enemy (standing firm) before them, and he said: "How bad is the habit your peers have given you! This is not how we used to fight alongside the Prophet (peace and blessings be upon him)." So he kept fighting until he was martyred. This hadith is sahih (authentic) on the condition of the two Shaykhs, but they did not record it.
