Sahih al-Bukhari, Volume 1, Book 12, Hadith 754 (USC-MSA) ⓘ

Narrated `Ikrima: I saw a person praying at Muqam-Ibrahim (the place of Abraham by the Ka`ba) and he was saying Takbir on every bowing, rising, standing and sitting. I asked Ibn `Abbas (about this prayer). He admonished me saying: "Isn't that the prayer of the Prophet?"

حَدَّثَنَا عَمْرُو بْنُ عَوْنٍ، قَالَ حَدَّثَنَا هُشَيْمٌ، عَنْ أَبِي بِشْرٍ، عَنْ عِكْرِمَةَ، قَالَ رَأَيْتُ رَجُلاً عِنْدَ الْمَقَامِ يُكَبِّرُ فِي كُلِّ خَفْضٍ وَرَفْعٍ وَإِذَا قَامَ وَإِذَا وَضَعَ، فَأَخْبَرْتُ ابْنَ عَبَّاسٍ ـ رضى الله عنه ـ قَالَ أَوَلَيْسَ تِلْكَ صَلاَةَ النَّبِيِّ صلى الله عليه وسلم لاَ أُمَّ لَكَ‏.‏
