٣ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ مُحَمَّدِ بْنِ يَحْيَى عَنْ غِيَاثِ بْنِ إِبْرَاهِيمَ عَنْ أَبِي عَبْدِ الله (عَلَيهِ السَّلام) قَالَ إِذَا سَلَّمَ مِنَ الْقَوْمِ وَاحِدٌ أَجْزَأَ عَنْهُمْ وَإِذَا رَدَّ وَاحِدٌ أَجْزَأَ عَنْهُمْ. 
3. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Muhammad ibn Yahya from Ghiyath ibn Ibrahim from Abu ‘Abdillah  who has said the following from the Imam: “If one person from a group offers the greeting of peace it is sufficient for all and so also is for an answer if only one person from the stationary group responds.”
