The mention by Al-Khasibi in his Water Poem of the times of prayer, obligatory (Fard) and supererogatory (Nawafil).

These are the fifty-one units mentioned by our master Abu Abd Allah al-Khasibi (may Allah honor his station) in his epistle as an explanation, and he recorded them in his Diwan as poetry. In total count, they are fifty-two units and fifty-two persons, because the two sitting units are counted as one unit in the outward form, according to their consensus that the Sitting Prayer (Salat al-Majalis) is valued at half of the Standing Prayer.

Muhammad then Fatir

And the two lions are roots

And all of them, and with them

They are the Guidance and the Path.

Master Muhammad (peace be upon him) is the person of the Zuhr (Midday) prayer, because it is the first prayer. He represents the persons of the "Ha's" (al-Hasan, al-Husayn, and al-Muhsin) and the beginning of their emergence from him.
