﴿ إِنَّ فِى ٱخْتِلَٰفِ ٱلَّيْلِ وَٱلنَّهَارِ وَمَا خَلَقَ ٱللَّهُ فِى ٱلسَّمَٰوَٰتِ وَٱلْأَرْضِ لَءَايَٰتٍۢ لِّقَوْمٍۢ يَتَّقُونَ ﴾

“for, verily, in the alternating of night and day, and in all that God has created in the heavens and on earth there are messages indeed for people who are conscious of Him!”

Truly in the alternation, of the night of the victory of the darkness of the soul over the heart and the day of the irradiation of the light of the spirit upon this [heart] and [in] what God has created in the heavens of spirits and the earth of bodies, there are signs for a people who fear, the veils of the attributes of the commanding-soul and who have attained the level of the self-reproaching soul and have recognised these signs.
