Safwan bin Mahraz narrates: When the last moments of Sayyiduna Abu Musa Ash'ari (may Allah be pleased with him) approached and people began to wail loudly over him, he said: The Noble Prophet (peace and blessings be upon him) said: "He is not from among us who wails and cries loudly (at the time of calamity), who tears (his collar), and who shaves his head."
