Hadith.5755 - Imam Ali ibn Musa Ar-Ridha عليه السلام wrote to Muhammad ibn Sinan in response to his questions: "The reason women are given half of what men receive from inheritance is because when a woman marries, she receives, whereas a man gives. Therefore, more has been allocated to men." Imam عليه السلام continued: "Another reason for giving the male twice as much as the female is that the female is under the care of the male if she is in need, and it is his responsibility to support her and provide for her. However, a woman is not required to support a man, nor is she responsible for his expenses if he is in need. Therefore, more has been allocated to the man for this reason. This is in accordance with the saying of Allah سبحانه وتعالى, the Mighty and Majestic: 'Men are the protectors and maintainers of women because Allah سبحانه وتعالى has given one more (strength) than the other and because they spend from their wealth.'" (Surah An-Nisa 4:34).
