It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) made a bequest at the time of his death and said: Concerning kalalah, the view is what I said. Ibn Abbas (may Allah be pleased with them both) asked: What did you say? He said: "One who has no child (is kalalah)." This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it. In origin it is musnad (traced back to the Prophet), because Umar (may Allah be pleased with him) said in his sermon that he had not referred to the Messenger of Allah (peace and blessings be upon him) on any matter as often as he did on the matter of kalalah.

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that a man said: O Messenger of Allah! What is kalalah? He (peace and blessings be upon him) said: "Have you not heard the verse that was revealed in the summer: 'They ask you for a ruling. Say: Allah gives you a ruling concerning kalalah' [Surah al-Nisa: 176] ? Kalalah is the one who leaves behind neither a child nor a father." This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs did not record it.
