Riyad as-Salihin Hadith 1414

A bedouin came to the Messenger of Allah (ﷺ) and said to him, "Teach me a few words to recite frequently." He (ﷺ) said, "Say: "La ilaha illallahu wahdahu la sharika lahu; Allahu Akbar kabiran, wal-hamdu lillahi kathiran, wa subhan-Allahi Rabbil-'alamin; wa la hawla wa la quwwata illa billahil-'Azizil-Hakim (there is no true god except Allah the One and He has no partner with Him; Allah is the Greatest and greatness is for Him. All praise is due to Him. Allah, the Rubb of the worlds is free from imperfection; there is no might and power but that of Allah, the All-Powerful and the All-Wise.)"' The bedouin said: "All of these for my Rubb. But what is for me?" Thereupon he (Messenger of Allah (ﷺ)) said, "You should say: 'Allahummaghfir li, warhamni, wahdini, warzuqni (O Allah! Grant me pardon, have mercy upon me, direct me to righteousness and provide me subsistence)'." [Muslim].
