Mukhtasar Bukhari

Lady Asma bint Abi Bakr Siddiq (may Allah be pleased with her) says that the Noble Prophet (peace and blessings of Allah be upon him) said to me: "O Asma! Do not withhold charity, otherwise blessings from your sustenance will also be withheld." In another hadith, these words are also mentioned: "Do not count your wealth and property, otherwise Allah will also give to you by counting (i.e., give charity without measure, and Allah Almighty will also give you abundantly)."
