Hazrat Ibn Abbas (may Allah be pleased with them both) narrated that the Prophet Muhammad (peace and blessings be upon him) used to say: "I seek refuge in Your honor; there is no deity except You. You are the One who never dies, while jinn and mankind will perish."
Hazrat Abu Musa (may Allah be pleased with him) narrated that the Noble Prophet (peace and blessings be upon him) used to supplicate: "My Lord! Forgive my mistakes, my ignorance, and my exceeding the limits in all my matters, and those sins which You know better than I do. O Allah! Forgive me in my errors, my intentional and unintentional actions, and in my jesting, and all of these are from me. O Allah! Forgive me for what I have done and what I will do, and for what I have concealed and what I have made apparent. You are the First and You are the Last, and You have power over everything."

Hadith 1738
1738 صحيح حديث أَبِي هُرَيْرَةَ رضي الله عنه أَنَّ رَسُولَ اللهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ، كَانَ يَقُولُ: لاَ إِلهَ إِلاَّ اللهُ وَحْدَهُ أَعَزَّ جُنْدَهُ وَنَصَرَ عَبْدَهُ وَغَلَبَ الأَحْزَابَ وَحْدَهُ فَلاَ شَيْءَ بَعْدَهُ
Hazrat Abu Huraira (may Allah be pleased with him) narrated that the Noble Prophet (peace and blessings of Allah be upon him) said: There is no deity except Allah, He is alone, who granted victory to His army, helped His servant (i.e., the Holy Prophet, peace be upon him), and single-handedly routed the confederates (i.e., the armies of the disbelievers). Thus, after this, nothing can stand against Him.
