Mukhtasar Bukhari

Abu Musa (may Allah be pleased with him) says that when a petitioner would come to the Messenger of Allah (peace and blessings of Allah be upon him) or something would be asked from him, he (peace be upon him) would say: "Intercede (recommend) for him (to help him), and you will be rewarded for it, and Allah causes what He wills to be decreed through the tongue of His Prophet."

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)."
