Muhammad ibn al-Hasan al-Saffar, from Ya'qub ibn Yazid, from al-Hasan ibn Ali al-Washsha, from al-Qasim ibn Burayd, from al-Fudayl, from Abu Abdillah عليه السلام, peace be upon him, who said: Imam عليه السلام said: "Whoever finds the coolness of our love in his liver, let him praise almighty Allah سبحانه وتعالى for the first of blessings." He said: “I asked, ‘May I be made your ransom, what is the first of blessings?’” Imam عليه السلام said: "Purity of birth." Then Abu Abdillah عليه السلام, peace be upon him, said: "The Commander of the Believers عليه السلام, peace be upon him, said to Sayyidah Fatimah صلى الله عليه وعلى آله وسلم, peace be upon her: 'Make your share of the fay' lawful for the fathers of our Shia, so that they may become pure.'" Then Abu Abdillah عليه السلام, peace be upon him, said: "Indeed, we (Ahlul Bayt عليه السلام) have made lawful for the fathers of our Shia that by which their mothers became lawful to them, so that their birth may be pure." – meaning made lawful their right/share in wealth connected to marriage, dowries, livelihood, or intimacy, so that the Shia’s births are pure and legitimate, unlike others.
