It is narrated from Sayyiduna Awf bin Malik (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "There is no Muslim who has three daughters and spends on them until they are married or they die, except that they will be a screen for him from the Fire." A woman asked: Or two daughters? He (peace and blessings be upon him) said: "And two as well."
