Sayyidah Ra'itah (may Allah be pleased with her) said: I asked the Prophet (peace and blessings be upon him), saying: "I am a woman with a craft by which I earn, and neither I, nor my husband, nor my children have anything; they keep me busy so that I do not give charity." He (peace and blessings be upon him) said: "You have in that the very reward of what you have spent on them."
