The Book of Prayer
وَلِمُسْلِمٍ عَنْ مَالِكِ بْنِ الْحُوَيْرِثِ - رضى الله عنه - نَحْوُ حَدِيثِ اِبْنِ عُمَرَ , وَلَكِنْ قَالَ : { حَتَّى يُحَاذِيَ بِهِمَا فُرُوعَ أُذُنَيْهِ } [1] .
Muslim has a Hadith narrated by Malik bin Huwairith (ﷺ) similar to the Hadith narrated by Ibn 'Umar (RA). But he (Malik bin Huwairith) mentioned: "He [the Prophet (ﷺ)] raised his hands parallel to the end of his ears."
