4. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad ibn ‘Isa from Safwan ibn Yahya who has said the following: “Once I was in the presence of al-Rida  and he sneezed. I said, ‘May Allah grant you al-Salat (favors).’ He sneezed again, and said, ‘May Allah grant you favors.’ He sneezed again and I said, ‘May Allah grant you favors.’ I then said, ‘May Allah keep my soul in service for your cause, if one like you (Imam) would sneeze should we say what we say to each other like: “May Allah grant you mercy? Or should we say what I just said, ‘(May Allah grant you al- Salat ’ ?’” The Imam said, ‘Yes, do you not say, “O Lord, grant al- Salat upon Muhammad and the Ahl al-Bayt, family of Muhammad?”’ I said, ‘Yes, we do.’ The Imam said, ‘Do you not say, “(O Lord,) be merciful to Muhammad and the Ahl al-Bayt, family of Muhammad?”’ Then the Imam said, ‘Yes, Allah grants al-Salat to him and has been merciful to him. Our saying, “May Allah grant him al-Salat is a blessing for us and a way of our seeking nearness to Allah (thereby).””’
