Excellence of sending prayers upon the Prophet (ﷺ)
وَقَالَ صلى الله عليه وسلم: (لاَ تَجْعَلُوا قَبْرِي عِيداً وَصَلُّوا عَلَيَّ؛ فَإِنَّ صَلاَتَكُم تَبْلُغُنِي حَيْثُ كُنْتُمْ)
-- The Prophet (ﷺ) said: "Do not make my grave a place of ritual celebration, but pray for Allah's blessings upon me, for your blessings reach me from wherever you are. Reference: Abu Dawud 2/218, Ahmad 2/367. Al-Albani graded it authentic in Sahih Abu Dawud 2/383.
