Narrated Samura:
حَدَّثَنَا مُؤَمَّلٌ ، حَدَّثَنَا إِسْمَاعِيلُ ، حَدَّثَنَا عَوْفٌ ، حَدَّثَنَا أَبُو رَجَاءٍ ، حَدَّثَنَا سَمُرَةُ ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " أَتَانِي اللَّيْلَةَ آتِيَانِ، فَأَتَيْنَا عَلَى رَجُلٍ طَوِيلٍ، لاَ أَكَادُ أَرَى رَأْسَهُ طُولاً، وَإِنَّهُ إِبْرَاهِيمُ صلى الله عليه وسلم " .
Allah's Messenger (ﷺ) said, "Two persons came to me at night (in dream) (and took me along with them). We passed by a tall man who was so tall that I was not able to see his head and that person was Abraham."
