It is narrated from Sayyiduna Abu Barzah (may Allah be pleased with him), he says: We were on a journey with the Messenger of Allah (peace and blessings be upon him), and he heard two individuals singing, responding to each other. One of them said: The bones of my helpers remained visible (because they were not buried), he refrained from removing the battle from himself until he was hidden and buried under the earth. The Noble Prophet (peace and blessings be upon him) said: See, who are these? The people said: These are so-and-so and so-and-so. He (peace and blessings be upon him) said: O Allah! Make the hair of their heads fall out and reject them into Hell.
