Remembrance 12 from Chapter 1
What has been narrated about the virtue of dhikr and is not restricted to a specific time
Lā ilāha illa-llāh, waḥdahu lā sharīka lah, lahu-l-mulku wa lahu-l-ḥamd, wa Huwa ‘alā kulli shay’in qadīr. Subḥāna-llāhi wa bi-ḥamdihi.
We relate in the Ṣaḥīḥs of Muslim and al-Bukhārī that Abū Hurayrah 
stated that the Messenger of Allah 
said: “Whoever says one hundred times a day There is no god but Allah, One without partners; His is the kingdom and His is the praise, and He has power over all things will be like someone who has set free ten slaves. One hundred good deeds will be written for him, one hundred of his sins will be forgiven, and it will be a shield for him against Shayṭān for that day until the evening. No one can produce anything better than it, except a man who does more than him. And whoever says Glory be to Allah and with His praise one hundred times a day will have his sins forgiven, even if they be [as abundant] as the foam of the sea.” [13].
