Imam Sadiq (peace be upon him): al-Kalbi narrated from Imam Sadiq (peace be upon him) that he said to me: "How many names does Muhammad (peace be upon him and his family) have in the Quran?" I said: "Two or three names." He said: "O Kalbi! He has ten names; وَ ما مُحَمَّدٌ إِلَّا رَسُولٌ قَدْ خَلَتْ مِنْ قَبْلِهِ الرُّسُلُ [Muhammad is only a Messenger of Allah, and messengers came before him too] (Al Imran/144), and مُبَشِّراً بِرَسُولٍ یَأْتِی مِنْ بَعْدِی اسْمُهُ أَحْمَدُ [and a bringer of glad tidings of a Messenger who will come after me whose name is Ahmad] (Saff/6), and وَ أَنَّهُ لَمَّا قامَ عَبْدُ اللهِ یَدْعُوهُ کادُوا یَکُونُونَ عَلَیْهِ لِبَداً [and when the servant of Allah [Muhammad] rose to worship and call upon Him, a group crowded densely around him] (Jinn/19), and طه ما أَنْزَلْنا عَلَیْکَ الْقُرْآنَ لِتَشْقی [Ta Ha, We have not sent down the Quran upon you that you should be distressed] (Ta Ha/2), and یس. وَ الْقُرْآنِ الْحَکِیمِ. إِنَّکَ لَمِنَ الْمُرْسَلِینَ. عَلی صِراطٍ مُسْتَقِیمٍ [Ya Sin. By the Wise Quran, indeed you are of the messengers [of Allah], on a straight path] (Ya Sin/4), and ن، وَ الْقَلَمِ وَ ما یَسْطُرُونَ. ما أَنْتَ بِنِعْمَةِ رَبِّکَ بِمَجْنُونٍ [Nun. By the pen and what they write, by the grace of your Lord you are not mad] (Qalam/2), and یا أَیُّهَا الْمُزَّمِّلُ [O you wrapped in your garment!] (Muzzammil/1), and یا أَیُّهَا الْمُدَّثِّرُ [O you enveloped in your cloak [reclining on the bed]!] (Muddaththir/1), and وَ قَدْ أَنْزَلَ اللهُ إِلَیْکُمْ ذِکْراً رَسُولًا [Allah has indeed sent down to you a Reminder, a Messenger]; so 'Dhikr' (Reminder) is one of the names of Muhammad (peace be upon him and his family), and we are the People of the Dhikr." Then he said: "O Kalbi! Ask whatever you wish." But by Allah, the whole Quran slipped from my memory and I could not recall a single word of it to ask the Imam (peace be upon him) about.
