Abu Yunus (may Allah have mercy on him), the freed slave of Aisha (may Allah be pleased with her), narrates: Lady Aisha (may Allah be pleased with her) ordered me to write a copy of the Qur’anic manuscript and said: When you reach this verse ﴿Hafizoo 'ala as-salawati was-salatil wusta﴾ [سورة البقرة: 238], inform me. Abu Yunus (may Allah have mercy on him) says: When I reached this verse, I informed her, so the Mother of the Believers (may Allah be pleased with her) dictated to me (this also) «حَافِظُواعَلَىالصَّلَوَاتِوَالصَّلَاةِالْوُسْطَىوَصَلَاةِالْعَصْرِوَقُومُوالِلَّهِقَانِتِينَ» and said: I heard this from the Messenger of Allah (peace and blessings be upon him).
