6. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Safwan ibn Yahya who has said the following: “I once asked abu al-Hassan , about passing behind the Masjid of the Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, without offering al-Salam to the Holy Prophet. He (the Imam) replied, ’Abu al-Hassan , would not do so.’ I then asked, ’Would he enter the Masjid and offer al-Salam without approaching the grave?’ He (the Imam) replied, ‘No, he, however, would offer al-Salam when entering and when leaving (the Masjid) from a distance.’”
