Al-Matalib al-'Aliyah 3332 — Sending blessings upon the Prophet ﷺ

It is narrated from Thuwayr (may Allah have mercy on him), the freed slave of Banu Hashim, that he said: I asked Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) how blessings should be sent upon the Prophet (peace and blessings be upon him). Sayyiduna Ibn Umar (may Allah be pleased with them both) said: Say: 'Allahumma ij'al salawatika wa barakatika wa rahmataka ala sayyid al-mursalin, wa imam al-muttaqin, wa khatam al-nabiyyin, Muhammadin abdika wa rasulika, imam al-khayri wa qa'id al-khayr. Allahumma ib'athhu yawm al-qiyamati maqaman mahmudan yaghbituhu al-awwaluna wa al-akhirun, wa salli ala Muhammadin wa ala ali Muhammadin kama sallayta ala Ibrahima wa ali Ibrahima innaka Hamidun Majid' (O Allah, send down Your special favours, Your blessings and Your mercy upon the leader of the Messengers, the imam of the God-fearing and the Seal of the Prophets, Muhammad (peace and blessings be upon him), Your chosen servant and Your Messenger, the imam of goodness and the leader and guide to good. O Allah, on the Day of Resurrection raise him to that "praised station" [Surah al-Isra: 79] which the first and the last (all of them) will envy; and send down Your mercy upon Muhammad (peace and blessings be upon him) and his family just as You sent down mercy upon Ibrahim (peace be upon him) and his family; indeed You alone are Most Praiseworthy, the Possessor of grandeur and glory).
The imams of hadith have recorded this narration in their books; in it Sayyiduna Ibn Umar (may Allah be pleased with them both) taught extremely eloquent and comprehensive words of blessings and peace befitting the sacred status of the Prophet (peace and blessings be upon him).
