Kinanah bin Nu'aym al-Adawi (may Allah have mercy on him) said: We were with Sayyiduna Qabisah bin Mukhariq (may Allah be pleased with him) when a cousin of his came to him seeking help with the dowry (mahr) of his wife, and he promised to give it to him. Then Sayyiduna Qabisah (may Allah be pleased with him) said: I came to the Messenger of Allah (peace and blessings be upon him) seeking help with a guarantee, and he (peace and blessings be upon him) said: "O Qabisah, asking is permissible only for one of three" - and then he narrated a similar hadith.
