Sayyiduna Abu al-Muhabbarah (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "Whoever provides for two daughters, or two sisters, or two maternal aunts, or two paternal aunts, or two grandmothers, will be with me in Paradise like these two (fingers)." The Prophet (peace and blessings be upon him) said this while joining his index finger and the finger next to it (and then he further said): "If they are three, that person will be weighed down by debt, and if they are four or five, then O servants of Allah, go to him, lend to him, enter into partnership (mudarabah) with him, enter into partnership with him!"
Imam Tabarani recorded it; its chain contains a narrator, Yahya bin Abd al-Hamid al-Himmani, and he is da'if (weak).
