It is reported in a Hadīth that Sayyiduna Rasoolullah صلى الله عليه وسلم said;
“When you recite Durood at my grave, then I hear your Durood, and when you recite Durood from afar, then your Durood is conveyed to me (via the angels).”
In another Hadīth, Sayyiduna Rasoolullah صلى الله عليه وسلم mentioned;
“Whenever any person makes Salaam to me, then Allah Ta’ala (جل جلاله) allows my soul to be returned to my body until I reply to the Salaam.”
In yet another Hadīth, Sayyiduna Rasoolullah صلى الله عليه وسلم said;
“The one who comes to my grave and conveys Salaam, I will intercede for him on the Day of Qiyaamah “
Apart from the group of angels collecting and conveying the Durood of the Ummah to Sayyiduna Rasoolullah صلى الله عليه وسلم, it is also reported in some Ahādīth that Allah Ta’ala جل جلاله has appointed an angel to stand at the blessed grave of Sayyiduna Rasoolullah صلى الله عليه وسلم and convey the Durood and Salaam of the entire Ummah to Sayyiduna Rasoolullah صلى الله عليه وسلم. This angel has been blessed with the power of hearing the Durood of every Ummatī, wherever he may be in the world. The angel conveys the Durood and Salaam of the Ummah to Sayyiduna Rasoolullah صلى الله عليه وسلم saying; “O Rasoolullah صلى الله عليه وسلم ! So and so, the son of so and so, has conveyed Durood and Salaam upon you.”

يَا رَبِّ صَلِّ وَسَلِّمْ دَائِمَاً أَبَداً عَلَىْ حَبِيْبِكَ خَيْرِ الْخَلْقِ كُلِّهِمِ
“O Sustainer, shower Salaat and Salaam forever and ever upon Your beloved, who is the best of all creation.”
جَزَی اللہُ عَنَّا نَبِيَّنَا مُحَمَّدًا صَلَّی اللہُ عَلَیْه وسَلَّمَ بِمَا هُوَ أَھْلُهُ
May Allah Ta’ala جل جلاله reward Muhammad صلى الله عليه وسلم on our behalf such a reward that is due to Him.
