Remembrance 13 from Chapter 1
What has been narrated about the virtue of dhikr and is not restricted to a specific time
Lā ilāha illa-llāhu, waḥdahu lā sharīka lah, Allāhu akbaru kabīran wa-l-ḥamdu li-llāhi kathīrā, subḥāna-llāhi Rabbī-l-‘ālamīn, lā ḥawla wa lā quwwata illā bi-llāhi-l-‘Azīzi-l-Ḥakīm. Allāhumma-ghfir lī wa-rḥamnī wa-hdinī wa-rzuqnī.
And we relate from the Ṣaḥīḥ of Muslim that Sa‘d ibn Abī Waqqāṣ 
reported that a Bedouin came to the Messenger of Allah 
and said: “Teach me something to say.” He replied: “Say: There is no god but Allah, One, without partners. Allah is vastly greater and abundant praise is due to Allah. Glory be to Allah, the Lord of the Worlds. There is no power and no strength except through Allah, the Mighty, the All-Wise.” The man said: “Those words are for my Lord. But what is for me?” He replied: “O Allah, forgive me, have mercy on me, guide me and sustain me.” [16].
