Sayyiduna Abu Musa Ash'ari (may Allah be pleased with him) narrated that the Prophet Muhammad (peace and blessings be upon him) said: "A time will surely come upon the people when a man will go out with his charity of gold but will not find anyone to accept it. And it will also happen that forty women will be under the protection of one man, because of the scarcity of men and the abundance of women." (Near the Day of Judgment, either the birth rate of women will increase and men will be fewer, or due to the abundance of wars, the number of men will decrease, and this has happened several times.)
