حَدَّثَنَا أَسْبَاطٌ وَابْنُ فُضَيْلٍ الْمَعْنَى قَالَا حَدَّثَنَا مُطَرِّفٌ عَنْ أَبِي الْجَهْمِ عَنْ أَبِي الرَّضْرَاضِ عَنِ ابْنِ مَسْعُودٍ قَالَ كُنْتُ أُسَلِّمُ عَلَى النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَهُوَ فِي الصَّلَاةِ فَيَرُدُّ عَلَيَّ فَسَلَّمْتُ عَلَيْهِ ذَاتَ يَوْمٍ فَلَمْ يَرُدَّ عَلَيَّ شَيْئًا فَوَجَدْتُ فِي نَفْسِي فَقُلْتُ يَا رَسُولَ اللَّهِ كُنْتُ أُسَلِّمُ عَلَيْكَ وَأَنْتَ فِي الصَّلَاةِ فَتَرُدُّ عَلَيَّ وَإِنِّي سَلَّمْتُ عَلَيْكَ فَلَمْ تَرُدَّ عَلَيَّ شَيْئًا فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِنَّ اللَّهَ يُحْدِثُ فِي أَمْرِهِ مَا يَشَاءُ
مسند امام احمد بن حنبل · Hadith 3944
It was narrated that Ibn Mas'ood said: I used to greet the Prophet (PBUH) with salam when he was praying and he would return the greeting. Then I greeted him with sal mu one day and he did not say anything to me in response, and I felt upset. I said: O Messenger of Allah, I used to greet you with salam when you were praying and you would return my greeting. Then I greeted you with salam and you did not say anything to me in response. The Messenger of Allah (PBUH) said: "Verily Allah introduces into His matter (i.e. religion) whatever He wants”.
