عَنْ عُبَيْدِ اللَّهِ بْنِ أَبِي طَلْحَةَ عَنْ أَبِيهِ رَضِيَ اللَّهُ عَنْهُ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ جَاءَ ذَاتَ يَوْمٍ وَالسُّرُورُ يُرَى فِي وَجْهِهِ فَقَالُوا يَا رَسُولَ اللَّهِ إِنَّا لَنَرَى السُّرُورَ فِي وَجْهِكَ فَقَالَ إِنَّهُ أَتَانِي مَلَكٌ فَقَالَ يَا مُحَمَّدُ أَمَا يُرْضِيكَ أَنَّ رَبَّكَ عَزَّ وَجَلَّ يَقُولُ إِنَّهُ لَا يُصَلِّي عَلَيْكَ أَحَدٌ مِنْ أُمَّتِكَ إِلَّا صَلَّيْتُ عَلَيْهِ عَشْرًا وَلَا يُسَلِّمُ عَلَيْكَ أَحَدٌ مِنْ أُمَّتِكَ إِلَّا سَلَّمْتُ عَلَيْهِ عَشْرًا قَالَ بَلَى
It is narrated from Sayyiduna Abu Talhah (may Allah be pleased with him), he says: One day the Messenger of Allah (peace and blessings be upon him and his family) came to us and signs of happiness were visible on his blessed face. We said: O Messenger of Allah! We see joy on your face. The Prophet (peace and blessings be upon him and his family) said: (The reason is that) an angel came to me and said: O Muhammad! Does it not please you that Allah Almighty says: Whoever from your Ummah sends blessings upon you once, I will send ten mercies upon him, and whoever from your Ummah prays for peace upon you once, I will send ten peaces upon him? I said: Why not, I am pleased.
