Whoever, while calling a friend, omits a letter from his name
Sahih Bukhari
حَدَّثَنَا أَبُو الْيَمَانِ، أَخْبَرَنَا شُعَيْبٌ، عَنِ الزُّهْرِيِّ، قَالَ حَدَّثَنِي أَبُو سَلَمَةَ بْنُ عَبْدِ الرَّحْمَنِ، أَنَّ عَائِشَةَ ـ رضى الله عنها ـ زَوْجَ النَّبِيِّ صلى الله عليه وسلم قَالَتْ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " يَا عَائِشَ هَذَا جِبْرِيلُ يُقْرِئُكِ السَّلاَمَ ". قُلْتُ وَعَلَيْهِ السَّلاَمُ وَرَحْمَةُ اللَّهِ. قَالَتْ وَهْوَ يَرَى مَا لاَ نَرَى.
Narrated `Aisha: (the wife the Prophet) Allah's Messenger (ﷺ) said, "O Aisha! This is Gabriel sending his greetings to you." I said, "Peace, and Allah's Mercy be on him." `Aisha added: The Prophet (ﷺ) used to see things which we used not to see.
