The Messenger of Allah ﷺ came one day with a joyful expression on his face. He said: "Jibril came to me and said: 'Will it not please you, O Muhammad, (to know) that no one of your Ummah will send salah upon you but I will send salah upon him tenfold, and no one will send salams upon you but I will send salams upon him tenfold?"
أَنَّ رَسُولَ اللَّهِ ﷺ جَاءَ ذَاتَ يَوْمٍ وَالْبِشْرُ يُرَى فِي وَجْهِهِ فَقَالَ إِنَّهُ جَاءَنِي جِبْرِيلُ ﷺ فَقَالَ أَمَا يُرْضِيكَ يَا مُحَمَّدُ أَنْ لاَ يُصَلِّيَ عَلَيْكَ أَحَدٌ مِنْ أُمَّتِكَ إِلاَّ صَلَّيْتُ عَلَيْهِ عَشْرًا وَلاَ يُسَلِّمَ عَلَيْكَ أَحَدٌ مِنْ أُمَّتِكَ إِلاَّ سَلَّمْتُ عَلَيْهِ عَشْرًا
