‘Ā'ishah, the wife of the Prophet (may Allah's peace and blessings be upon him), reported: Al-Hawlā' bint Tuwayt ibn Habīb ibn ‘Abd al-‘Uzza passed while I was sitting with the Messenger of Allah, may Allah’s peace and blessings be upon him. So I said: "This is Al-Hawlā' bint Tuwayt, and they claim that she does not sleep at night." Upon hearing this, the Messenger of Allah (may Allah’s peace and blessings be upon him) said: "She does not sleep at night! Do what you are capable of doing (regularly). By Allah, Allah never grows weary (of giving rewards) until you grow weary (of doing good deeds).” [Sahih/Authentic] - [Al-Bukhari and Muslim]

عن عائشة زوجِ النبي -صلى الله عليه وسلم-، أخبرته أنَّ الحَوْلاء بنت تُوَيت بن حبيب بن أسد بن عبد العُزَّى مرَّت بها وعندها رسول الله -صلى الله عليه وسلم-، فقلتُ: هذه الحَوْلاء بنت تُوَيت، وزعموا أنها لا تنام الليلَ، فقال رسول الله -صلى الله عليه وسلم-: «لا تنامُ الليلَ! خذوا مِن العمل ما تُطِيقون، فواللهِ لا يسأمُ اللهُ حتى تسأموا».
