In the morning say,

اَللّٰهُمَّ مَا أَصْبَحَ بِيْ مِنْ نِعْمَةٍ أَوْ بِأَحَدٍ مِنْ خَلْقِكَ فَمِنْكَ وَحْدَكَ لَا شَرِيْكَ لَكَ، فَلَكَ الْحَمْدُ وَلَكَ الشُّكْرُ

O Allaah, what blessing I have received in this morning or any of Your creation, is from You alone, without any partner, so for You is all praise and unto You all thanks.

Allaahumma maa 'asbaha bee min ni'matin 'aw bi'ahadin min khalqika faminka wahdaka laa shareeka laka, falakal-hamdu wa lakash-shukru.

In the evening say,

اَللّٰهُمَّ مَا أَمْسَى بِيْ مِنْ نِعْمَةٍ أَوْ بِأَحَدٍ مِنْ خَلْقِكَ فَمِنْكَ وَحْدَكَ لَا شَرِيْكَ لَكَ، فَلَكَ الْحَمْدُ وَلَكَ الشُّكْرُ

O Allaah, what blessing I have received in this evening or any of Your creation, is from You alone, without any partner, so for You is all praise and unto You all thanks.

Allaahumma maa 'amsaa bee min ni'matin 'aw bi'ahadin min khalqika faminka wahdaka laa shareeka laka, falakal-hamdu wa lakash-shukru.

Whoever recites this in the morning, has completed his obligation to thank Allah for that day; and whoever says it in the evening, has completed his obligation for that night
