Sayyiduna Abdullah bin Amir (may Allah be pleased with him) sent maintenance and clothing to Sayyidah Aishah (may Allah be pleased with her). Sayyidah Aishah (may Allah be pleased with her) said to the one who brought it: "My son, I do not take anything from anyone." When he had left, she said: "Call him back." Then she said: "I remembered that the Messenger of Allah (peace and blessings be upon him) said to me: 'O Aishah, whoever gives you something without your asking, accept it, for it is provision that Allah has given you.'"
