Abu Talha told of God’s Messenger coming one day with a cheerful look on his face and saying: Gabriel came to me and told me that my Lord says, “Does it not please you, Muhammad, that none of your people will invoke a blessing on you without my blessing him ten times, and that none of your people will give you a greeting without my greeting him ten times?” Nasa’i and Darimi transmitted it.

وَعَن أبي طَلْحَة أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ جَاءَ ذَاتَ يَوْمٍ وَالْبِشْرُ فِي وَجْهِهِ فَقَالَ: " إِنَّهُ جَاءَنِي جِبْرِيلُ فَقَالَ: إِنَّ رَبَّكَ يَقُولُ أَمَا يُرْضِيكَ يَا مُحَمَّدُ أَنْ لَا يُصَلِّيَ عَلَيْكَ أَحَدٌ مِنْ أُمَّتِكَ إِلَّا صَلَّيْتُ عَلَيْهِ عَشْرًا وَلَا يُسَلِّمُ عَلَيْكَ أَحَدٌ مِنْ أُمَّتِكَ إِلَّا سَلَّمْتُ عَلَيْهِ عَشْرًا؟ ". رَوَاهُ النَّسَائِيُّ وَالدَّارِمِيُّ
