وَعَنْ أَبِي مَسْعُودٍ الْأَنْصَارِيِّ
قَالَ: نَهَى رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: أَنْ يَقُومَ الْإِمَامُ فَوْقَ شَيْءٍ وَالنَّاسُ خَلْفَهُ يَعْنِي أَسْفَلَ مِنْهُ
Abu Masud al-Ansari said God’s messenger forbade that the imam should stand on anything when the people were behind him, meaning on a lower level than he was. Daraqutnl transmitted it in al-Mujtaba in Kitab al-janaiz.
