Al-Bukhari recorded that Abu Sa`id Al-Khudri, may Allah be pleased with him, said: "We said, `O Messenger of Allah, this is the Salam upon you, but how do we send Salah upon you' He said:

«قُولُوا: اللَّهُمَّ صَلِّ عَلَى مُحَمَّدٍ عَبْدِكَ وَرَسُولِكَ، كَمَا صَلَّيْتَ عَلَى آلِ إِبْرَاهِيمَ ، وَبَارِكْ عَلَى مُحَمَّدٍ وَعَلَى آلِ مُحَمَّدٍ، كَمَا بَارَكْتَ عَلَى آلِ إِبْرَاهِيم»

(Say: "O Allah, send Your Salah upon Muhammad, Your servant and Messenger, as You sent Your Salah upon the family of Ibrahim, and send Your blessings upon Muhammad and upon the family of Muhammad, as You sent Your blessings upon the family of Ibrahim.'')'' Abu Salih narrated that Layth said:

«عَلَى مُحَمَّدٍ وَعَلَى آلِ مُحَمَّدٍ، كَمَا بَارَكْتَ عَلَى آلِ إِبْرَاهِيم»

(Upon Muhammad and upon the family of Muhammad as You sent Your blessings upon the family of Ibrahim.) Ibrahim bin Hamzah told that, Ibn Abi Hazim and Ad-Darawardi told, that Yazid, i.e., Ibn Al-Had said:

«كَمَا صَلَّيْتَ عَلَى إِبْرَاهِيمَ ، وَبَارِكْ عَلَى مُحَمَّدٍ وَآلِ مُحَمَّدٍ، كَمَا بَارَكْتَ عَلَى إِبْرَاهِيمَ وَ آلِ إِبْرَاهِيم»

(As You sent Your Salah upon Ibrahim, and send Your blessings upon Muhammad and the family of Muhammad, as You sent Your blessings upon Ibrahim and the family of Ibrahim.) This was also recorded by An-Nasa'i and Ibn Majah.
