[Machine] No one had greater sanctity than the Messenger of Allah ﷺ . When the companions of the Messenger of Allah ﷺ wrote to him, they would write "From so-and-so to Muhammad, the Messenger of Allah ﷺ ."
لَمْ يَكُنْ أَحَدٌ أَعْظَمَ حُرْمَةً مِنْ رَسُولِ اللهِ ﷺ كَانَ أَصْحَابُ رَسُولِ اللهِ ﷺ إِذَا كَتَبُوا إِلَيْهِ يَكْتُبُونَ مِنْ فُلَانٍ إِلَى مُحَمَّدٍ رَسُولِ اللهِ ﷺ
