Abu Salamah bin Abd al-Rahman (may Allah have mercy on him) said: A man came to the Prophet (peace and blessings be upon him) and asked: O Messenger of Allah! "They ask you for a ruling. Say: Allah gives you a ruling concerning kalalah" [Surah al-Nisa: 176]. He (peace and blessings be upon him) said: "Whoever leaves neither children nor parents, his heirs are kalalah."
Abu Dawud (may Allah have mercy on him) said: It is reported from al-Bara' (may Allah be pleased with him) concerning kalalah: "The verse of the summer will suffice you."
This (report of al-Bara') is the well-known one; the report of Abu Ishaq from Abu Salamah is munqati' (with a broken chain) and is not ma'ruf (well known).
