حَدَّثَنَا مُحَمَّدُ بْنُ يَحْيَى، قَالَ: ثَنَا جَعْفَرُ بْنُ عَوْنٍ، قَالَ: ثَنَا هِشَامُ بْنُ سَعْدٍ، قَالَ: ثَنَا نَافِعٌ، سَمِعْتُ عَبْدَ اللَّهِ بْنَ عُمَرَ، رَضِيَ اللَّهُ عَنْهُمَا يَقُولُ: خَرَجَ رَسُولُ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ إِلَى قُبَاءٍ يُصَلِّي فِيهِ قَالَ: فَجَاءَتِ الْأَنْصَارُ فَسَلَّمُوا عَلَيْهِ وَهُوَ يُصَلِّي قَالَ: فَقُلْتُ: يَا بِلَالُ كَيْفَ رَأَيْتَ رَسُولَ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ يَرُدُّ عَلَيْهِمْ حِينَ كَانُوا يُسَلِّمُونَ عَلَيْهِ وَهُوَ يُصَلِّي؟ قَالَ: يَقُولُ هَكَذَا وَبَسَطَ كَفَّهُ
Abdullah bin Abbas (may Allah be pleased with them both) narrates that the Messenger of Allah (peace and blessings be upon him) went to Masjid Quba to offer prayer. He was praying when the Ansar came and greeted him with Salam. Abdullah bin Umar (may Allah be pleased with them both) says: I asked, "O Bilal! How did you see the Messenger of Allah (peace and blessings be upon him) respond to Salam during prayer?" He spread out his pouch and said: "Like this."
