Narrator:Abdullāh ibn ‘Umar
حَدَّثَنَا مَحْمُودُ بْنُ غَيْلاَنَ، حَدَّثَنَا وَكِيعٌ، حَدَّثَنَا هِشَامُ بْنُ سَعْدٍ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، قَالَ قُلْتُ لِبِلاَلٍ كَيْفَ كَانَ النَّبِيُّ صلى الله عليه وسلم
يَرُدُّ عَلَيْهِمْ حِينَ كَانُوا يُسَلِّمُونَ عَلَيْهِ وَهُوَ فِي الصَّلاَةِ قَالَ كَانَ يُشِيرُ بِيَدِهِ
Ibn Umar narrated:
"I said to Bilal: 'How did the Prophet (S) reply to them when they gave him Salams and he was performing Salat?' He said: 'He would motion with his hand.'"
