Hadith 1000
´Ali bin Rabi'ah Al-Asadi said:` "A man died among the Ansar named Qarazah bin Ka'b, and he was being wailed over. So Al-Mughirah bin Shu'bah came and ascended the Minbar. He uttered thanks and praise to Allah and said: "As for the gravity of wailing in Islam, indeed I heard the Messenger of Allah saying: 'The one who is wailed over is punished as long as he is being wailed over.'"
Hadith 1001
´Abu Hurairah narrated that the Messenger of Allah said:` "There are four matters in my nation that are from the matters of Jahiliyyah which the people will not leave: Wailing, slandering one's lineage, Al-Adwa - a camel gets mange, so one hundred camels get mange - but who gave the first camel mange? And Al-Anwa (saying): "We got rain because of this or that celestial positioning.'"
