Sayyida Aisha Siddiqa (may Allah be pleased with her) narrates: Once, Hawla bint Tuwait passed by her. The Prophet Muhammad (peace and blessings be upon him) was also present with her. Sayyida Aisha (may Allah be pleased with her) narrates: I said, "This is Hawla bint Tuwait. People say that she does not sleep at night." Sayyida Aisha (may Allah be pleased with her) narrates: The Prophet Muhammad (peace and blessings be upon him) said, "She does not sleep at night? You people should do as much (good) deeds as you have the strength for. By Allah! Allah’s bounty does not cease until you yourselves become weary."
