Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "Any member of my Ummah who has three daughters or three sisters and provides for them until they reach maturity, that person will be with me in Paradise like this." The Prophet (peace and blessings be upon him) said this while joining his index finger and middle finger together. (Allamah Haythami says:) I say: In the "Sahih" this is mentioned from this Companion: "Whoever provides for two girls".
Imam Tabarani recorded it in al-Mu'jam al-Awsat with two chains, and the narrators of one of them are the narrators of the Sahih.
