Pronunciation: Allahumma ma am-sa bî min ni'mah, Aw bi-aa-ha-dim-min khal-qika, Fa-min-ka wah-daka la sharî-ka laka, Fa-la-kal-hamdu wa la-kash-shukr.
Meaning: O Allah, what blessing I or any of Your creation have reached the evening upon, is from You alone, without partner, so for You is all praise and unto You all thanks.
Virtue: Whoever says this in the morning has indeed offered his day’s thanks and whoever says this in the evening has indeed offered his night’s thanks.
Note: For the morning one reads (as-ba-ha), and for the evening one reads (am-sa)
