Al-Husayn ibn Muhammad has narrated from Mu‘alla ibn Muhammad from Ahmad ibn Muhammad ibn ‘Abdallah from Ayyub ibn Nuh who has said the following. “I was in the presence of The Imam 
and he sneezed. I then asked him, “May Allah take my soul in service for your cause, what should one say when the Imam sneezes?” The Imam said, “One should say, ‘May Allah (grant) blessings (up on) you.’”
الْحُسَيْنُ بْنُ مُحَمَّدٍ عَنْ مُعَلَّى بْنِ مُحَمَّدٍ عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ عَبْدِ الله عَنْ أَيُّوبَ بْنِ نُوحٍ قَالَ عَطَسَ يَوْماً وَأَنَا عِنْدَهُ فَقُلْتُ جُعِلْتُ فِدَاكَ مَا يُقَالُ لِلامَامِ إِذَا عَطَسَ قَالَ يَقُولُونَ صَلَّى الله عَلَيْكَ.
Muhammad ibn Yahya has narrated from Ja‘far ibn Muhammad who has said that Ishaq ibn Ibrahim al-Daynuri narrated to me from ‘Umar ibn Zahir from abu ‘Abdallah . He has said that a man asked, “Is al-Qa’im (the one who will rise with Divine Authority) is offered the Islamic greeting as the commander of the faithful?” The Imam said, “No, because that is the name that Allah had given to Ali ibn abu Talib . Allah had not given this name to anyone before him. No one will be called with this name except an unbeliever.” I then said, “May Allah take my soul in service for your cause, what form of Islamic greeting would be offered to him?” The Imam said, “They will say, “Peace be up on you, O Baqiyya Allah (Allah’s reserved power to establish His authority on earth). He then recited, “If you are true believers then know that the profit which God has left for you is better for you (than what you may gain through deceitful ways). I am not responsible for your deeds.” (:86)
