Once I said, "O Allah's Messenger (ﷺ)! I have no property except what has been given to me by Az-Zubair (i.e. her husband). May I give in charity?" The Prophet (ﷺ) said, "Give in charity and do not withhold it; otherwise Allah will withhold it back from you . "
Allah's Messenger (ﷺ) said, "Give (in charity) and do not give reluctantly lest Allah should give you in a limited amount; and do not withhold your money lest Allah should withhold it from you."
My mother came to me during the lifetime of Allah's Messenger (ﷺ) and she was a pagan. I said to Allah's Apostle (seeking his verdict), "My mother has come to me and she desires to receive a reward from me, shall I keep good relations with her?" The Prophet (ﷺ) said, "Yes, keep good relation with her. "
