((اللَّهُمَّ إِنِّي أَصْبَحْتُ أُشْهِدُكَ، وَأُشْهِدُ حَمَلَةَ عَرْشِكَ، وَمَلاَئِكَتِكَ، وَجَمِيعَ خَلْقِكَ، أَنَّكَ أَنْتَ اللَّهُ لَا إِلَهَ إِلاَّ أَنْتَ وَحْدَكَ لاَ شَرِيكَ لَكَ، وَأَنَّ مُحَمَّداً عَبْدُكَ وَرَسُولُكَ)) (أربعَ مَرَّاتٍ).[ وإذا أمسى قال: اللَّهم إني أمسيت...]
(O Allah, verily I have reached the morning and call on You, the bearers of Your throne, Your angles, and all of Your creation to witness that You are Allah, none has the right to be worshipped except You, alone, without partner and that Muhammad is Your Servant and Messenger.) (four times in the morning & evening)(Note: for the evening, one reads (amsaytu) instead of (asbahtu).)
