عن أنس رضي الله عنه قال : قال رسول الله صلى الله عليه وسلم : خرج جبريل عليه السلام من عندي آنفا يخبرني عن ربه عز وجل : ما على الأرض مسلم صلى عليك واحدة إلا صليت عليه أنا وملائكتي عشرا، فأكثروا علي من الصلاة يوم الجمعة، وإذاصليتم علي فصلوا على المرسلين، فإني رجل من المرسلين (القول البديع ص250)

Hazrat Anas (radhiyallahu ‘anhu) reports that Rasulullah (sallallahu ‘alaihi wasallam) said, “Hazrat Jibreel (‘alaihis salaam) just departed from me now. He had come to inform me that Allah Ta‘ala said, ‘There is no muslim on the earth who recites durood upon you (i.e. on Rasulullah (sallallahu ‘alaihi wasallam)) once, except that I and My angels send durood upon him (i.e I shower ten mercies on him and my angels seek forgiveness for him ten times).’ Thus recite abundant durood upon me on the day of Jumu‘ah, and when you recite durood upon me, then send salutations upon the Ambiyaa (‘alaihimus salaam), as I am a Nabi among the Ambiyaa (‘alaihimus salaam).”

In this Hadith, Rasulullah (sallallahu ‘alaihi wasallam) has taught us that whenever we send durood on him, we should send salutations on the Ambiyaa (‘alaihimus salaam) as well. Hence, when we recite durood on Rasulullah (sallallahu ‘alaihi wasallam), we should add the following at the end:

وَعَلَى الْمُرْسَلِيْن

And on the Ambiyaa (‘alaihimus salaam) as well

يَا رَبِّ صَلِّ وَسَلِّمْ دَائِمًا اَبَدًا عَلَى حَبِيْبِكَ خَيْرِ الْخَلْقِ كُلِّهِمِ
