حَدَّثَنَا أَحْمَدُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا حَجَّاجٌ، عَنِ ابْنِ جُرَيْجٍ، أَخْبَرَنِي أَبُو خَالِدٍ، عَنْ عَدِيِّ بْنِ ثَابِتٍ الأَنْصَارِيِّ، حَدَّثَنِي رَجُلٌ، أَنَّهُ كَانَ مَعَ عَمَّارِ بْنِ يَاسِرٍ بِالْمَدَائِنِ فَأُقِيمَتِ الصَّلاَةُ فَتَقَدَّمَ عَمَّارٌ وَقَامَ عَلَى دُكَّانٍ يُصَلِّي وَالنَّاسُ أَسْفَلَ مِنْهُ فَتَقَدَّمَ حُذَيْفَةُ فَأَخَذَ عَلَى يَدَيْهِ فَاتَّبَعَهُ عَمَّارٌ حَتَّى أَنْزَلَهُ حُذَيْفَةُ فَلَمَّا فَرَغَ عَمَّارٌ مِنْ صَلاَتِهِ قَالَ لَهُ حُذَيْفَةُ أَلَمْ تَسْمَعْ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ ‏"‏إِذَا أَمَّ الرَّجُلُ الْقَوْمَ فَلاَ يَقُمْ فِي مَكَانٍ أَرْفَعَ مِنْ مَقَامِهِمْ ‏"‏ ‏.‏ أَوْ نَحْوَ ذَلِكَ قَالَ عَمَّارٌ لِذَلِكَ اتَّبَعْتُكَ حِينَ أَخَذْتَ عَلَى يَدَىَّ ‏.‏
Translation
‘Adi b. Thabit al-Ansari said; A man related to me that (once) he was in the company of ‘Ammar b. yasir in al-Mada’in (a city near Ku’fah). The IQAMAH was called for prayer

A man was with Ammar ibn Yasir in Al-Mada'in when the prayer was called. Ammar stepped forward and stood on a raised mound to pray, while the people were below him. Hudhayfah stepped forward, took him by his hands, and Ammar followed him until Hudhayfah brought him down. When Ammar finished his prayer, Hudhayfah said to him: Did you not hear the Messenger of Allah, peace and blessings be upon him, say: "When a man leads a people in prayer, he must not stand in a place higher than their position" or words to that effect? Ammar said: It was for that reason that I followed you when you took my hands.
