Hadith 15175

(حديث مرفوع) حَدَّثَنَا عَبْدُ الرَّزَّاقِ , أَخْبَرَنَا سُفْيَانُ , عَنْ أَبِي الزُّبَيْرِ ، عَنْ جَابِرٍ , قَالَ : بَعَثَنِي رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لِحَاجَةٍ , فَجِئْتُ وَهُوَ يُصَلِّي نَحْوَ الْمَشْرِقِ , وَيُومِئُ إِيمَاءً عَلَى رَاحِلَتِهِ , السُّجُودُ أَخْفَضُ مِنَ الرُّكُوعِ , فَسَلَّمْتُ عَلَيْهِ , فَلَمْ يَرُدَّ عَلَيَّ , قَالَ : فَلَمَّا قَضَى صَلَاتَهُ , قَالَ : " مَا فَعَلْتَ فِي حَاجَةِ كَذَا وَكَذَا ؟ إِنِّي كُنْتُ أُصَلِّي " .
It is narrated from Sayyiduna Jabir (may Allah be pleased with him) that the Prophet sent me on an errand while going towards Banu Mustaliq. When I returned, the Prophet (peace and blessings be upon him) was praying facing east on his camel. I wanted to speak, but the Prophet (peace and blessings be upon him) gestured with his hand. This happened twice. Then I heard the Prophet (peace and blessings be upon him) reciting, and he was gesturing with his head. After finishing the prayer, the Prophet (peace and blessings be upon him) said: What happened regarding the task I sent you for? I did not reply because I was praying.
