وَعَنِ
ابْنِ عَبَّاسٍ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَمَرَ بِسَدِّ الْأَبْوَابِ إِلَّا بَابَ عَلِيٍّ. رَوَاهُ التِّرْمِذِيُّ وَقَالَ: هَذَا حَدِيثٌ غَرِيبٌ
Translation
Ibn `Abbas told that God's messenger ordered all the doors [opening on the mosque] to be shut except `Ali's. Tirmidhi transmitted it, saying this is a gharib tradition.
