Narrated `Aisha:
حَدَّثَنَا قُتَيْبَةُ ، قَالَ حَدَّثَنَا سُفْيَانُ ، عَنِ الزُّهْرِيِّ ، عَنْ عُرْوَةَ ، عَنْ عَائِشَةَ ، أَنَّ النَّبِيَّ صلى الله عليه وسلم صَلَّى فِي خَمِيصَةٍ لَهَا أَعْلاَمٌ فَقَالَ " شَغَلَتْنِي أَعْلاَمُ هَذِهِ، اذْهَبُوا بِهَا إِلَى أَبِي جَهْمٍ وَأْتُونِي بِأَنْبِجَانِيَّةٍ " .
Once the Prophet (ﷺ) prayed on a Khamisa with marks on it and said, "The marks on it diverted my attention, take this Khamisa to Abu Jahm and bring an Inbijaniya (from him.)"
