Dawud :: Book 8 : Hadith 1503
Narrated Zayd ibn Arqam:
I heard the Apostle of Allah (peace_be_upon_him) saying (the version of Sulayman has: The Apostle of Allah (peace_be_upon_him) used to say) after his prayer:-
"O Allah, our Lord and Lord of everything, I bear witness that Thou art the Lord alone Who hast no partner; O Allah, Our Lord and Lord of everything, I bear witness that Muhammad is Thy servant and Thy apostle ; O Allah, our Lord and Lord of everything, I bear witness that all the servants are brethren; O Allah, our Lord and Lord of everything make me sincere to Thee, and my family too at every moment, in this world and in the world hereafter, O Possessor of glory and honour, listen to me and answer. Allah is incomparably great. O Allah, Light of the heavens and of the earth".
